Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an uplink channel power control method, apparatus, network-side device, and terminal. Background Art

[0002] In the NR system, the base station can configure the association relationship between the spatial-related parameters of the uplink channel resources and the power control parameters in the signaling for the terminal in space, and the terminal uses the power control parameters associated with the spatial-related parameters to determine the transmission power of the uplink channel resources. If the base station does not configure the spatial signaling for the terminal, the terminal uses specific power control parameters to determine the transmission power of the uplink channel resources.

[0003] In the new generation version of the NR system, the uplink channel transmission of M-TRP (Multi-Transmission / Receiption Point) is introduced, which can meet the requirements of ultra-high rate to a certain extent. The specific method is as follows: The M-TRP transmission is achieved through the repeated transmission of the uplink channel, where each TRP corresponds to a part of the repeated transmission of the uplink channel, and the repeated versions of the uplink channels corresponding to different TRPs are different.

[0004] In the uplink channel transmission mode of M-TRP, in the FR1 frequency band, the base station usually does not configure the spatial signaling for the terminal. If the above method is still used to determine the transmission power, the power control parameters of multiple TRPs are the same. However, in fact, due to the different physical positions of multiple TRPs, the path loss, the optimal target receiving power of the uplink channel resources, the closed-loop loop parameters, etc. may all be different. Therefore, it is not reasonable to use the same power control parameters. In the face of this situation, there is no association scheme between the uplink channel resources and the power control parameters in the prior art, which makes the base station and the terminal have no consistent understanding of the transmission power of the uplink channel, thus making the uplink channel transmission of M-TRP unable to work properly.

[0167] The embodiments of the present application provide an uplink channel power control method, device, network-side device, and terminal, for providing a dynamic indication method for uplink channel resource power control parameters.

[0168] Among them, the method and the device are based on the same inventive concept. Since the principles for solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0169] In addition, the technical solutions provided in the embodiments of the present application can be applied to multiple systems, especially 5G systems. For example, the applicable systems can be Global System of Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems, etc. Both terminal devices and network-side devices are included in these multiple systems. The system may also include a core network part, such as an Evolved Packet System (EPS), a 5G System (5GS), etc.

[0170] The terminal (device) involved in the embodiments of this application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device.

The wireless terminal device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, which is not limited in the embodiments of this application.

Depending on specific application scenarios, the base station can also be referred to as an access point, or it can be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or have other names. The network-side device can be used to mutually replace the received air frames with Internet Protocol (IP) packets and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network can include an IP communication network. The network-side device can also coordinate the management of the attributes of the air interface.

In some network architectures, the network-side device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0172] The network-side device and the terminal device can each use one or more antennas for multi-input multi-output (MIMO) transmission. The MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the form and quantity of the root antenna combination, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or it can be diversity transmission, precoding transmission, beamforming transmission, etc.

[0173] To better understand the solution of this application, the relevant content involved in the embodiments of this application will be briefly introduced below.

[0174] In the Rel-16 version of the NR system, the uplink channel transmission of S-TRP (Single Transmission and Reception Point) is supported. The open-loop parameters required for calculating the transmission power of the uplink channel resources can be determined according to the target reception power P 0 and the required path loss parameters can be determined according to the reference signal for measuring the path loss (path loss reference signal). The network-side device (taking the base station as an example for illustration), the base station can configure one or more P 0 , one or more path loss reference signals (in the system, it can be configured through the path loss reference signal pathlossReferenceRS), and can configure the closed-loop loop parameters. These configurations can be used for all the uplink channel resources exclusive to the terminal. For the uplink channel resources common to the cell, the base station will configure one or more corresponding P 0 .

[0175] The base station can configure the association relationship between the spatial relation information identifier SpatialRelationInfoId of the uplink channel resources and P 0 , the path loss reference signal, and the closed-loop loop parameters in the spatial relation information signaling SpatialRelationInfo. When the base station indicates a spatial relation information identifier (SpatialRelationInfoId) for an uplink channel resource, the terminal needs to use the reference signal included in the spatial related parameters to determine the spatial filter of the uplink channel resources, and use the P 0 , the path loss reference signal, and the closed-loop loop parameters associated in the spatial related parameters as the P 0 , the path loss reference signal, and the closed-loop loop parameters corresponding to the uplink channel resources.

[0176] If the base station does not configure the spatial relation information signaling SpatialRelationInfo for the terminal, but configures pathlossReferenceRS, the terminal uses a specific P 0 , path loss reference signal, and closed-loop loop parameters to determine the transmission power of the uplink channel resources.

[0177] In Release 17 of the NR system, the uplink channel transmission of multi-transmit receive point M-TRP was introduced. The specific method is as follows: M-TRP transmission is achieved through the repeated transmission of the uplink channel, where each TRP corresponds to the transmission of a part of the repeated copy of the uplink channel (which we will denote as uplink channel repetition below), and the uplink channel repetitions corresponding to different TRPs are different.

[0178] When the uplink channel supports M-TRP transmission, in the lower frequency band (such as the FR1 band), the base station does not need to indicate the spatial filtering value of the uplink channel resources, and the base station does not configure SpatialRelationInfo for the terminal. At this time, according to the previous introduction, the terminal uses a specific P 0 , path loss reference signal, and closed loop to determine the transmission power of the uplink channel resources.

[0179] In the uplink channel transmission mode of M-TRP, if the above determination method is still used, the P 0 , path loss reference signal, and closed-loop loop parameters of multiple TRPs are the same. However, in fact, due to the different physical positions of multiple TRPs, the path loss experienced by the uplink channel resources, the optimal P 0 and closed-loop loop parameters are very likely to be different. Therefore, in order to obtain better uplink channel transmission performance of M-TRP, a new uplink channel resource power control parameter determination scheme needs to be considered.

[0180] To support the indication of uplink channel resource power control parameters in the FR1 band for M-TRP, a possible way is that when the uplink channel resources supporting M-TRP are repeatedly transmitted, the base station is allowed to configure a set of power control parameters for each of the multiple TRPs in the RRC (Radio Resource Control) signaling. When the base station does not indicate SpatialRelationInfo to the terminal but configures pathlossReferenceRS, the repetitions corresponding to the multiple TRPs are respectively specific P 0 , path loss reference signal, and closed-loop loop parameters in their respective sets of power control parameters.

[0181] A possible way is to introduce an indication signaling to indicate whether the uplink channel resources are S-TRP transmission or M-TRP transmission.

[0182] An embodiment of the present application provides a dynamic indication method for uplink channel resource power control parameters, which solves the problem of power control of the uplink channel under M-TRP when the base station does not configure SpatialRelationInfo for the terminal.

[0183] See Figure 1 , Figure 1 shows a schematic flowchart of an uplink channel power control method provided by an embodiment of the present application. The method is applied to a network-side device, and the method includes:

[0184] Step 101: Indicate information for determining the transmission power of uplink channel resources through a first target signaling; wherein, the information for determining the transmission power of uplink channel resources indicated by the first target signaling includes at least one of the following: indication information of power control parameters, indication information of a set of power control parameters; the indication information of the power control parameters indicates one or more power control parameters through at least one of the following: identification information of the power control parameters, the number of power control parameters, and the group of the power control parameters.

[0185] Here, the network-side device dynamically indicates the information for determining the transmission power of uplink channel resources through the first target signaling. When the network-side device does not configure a spatial setting signaling for the terminal, the network-side device and the terminal can also have a consistent understanding of the transmission power of the uplink channel resources, ensuring the normal operation of the uplink channel transmission of M-TRP. Among them, the information for determining the transmission power of uplink channel resources indicated in the first target signaling may include indication information of power control parameters and indication information of a set of power control parameters. The indication information of the power control parameters can indicate one or more power control parameters in various ways such as indicating the identification information, number, and group of the power control parameters. The indication method is flexible and highly operable.

[0186] Among them, the network-side device can configure one or more power control parameters for the uplink channel resources through RRC signaling.

[0187] Among them, the power control parameters may include at least one of the following: target received power P 0 , path loss reference signal, closed-loop reference signal, but not limited thereto.

[0188] Among them, the power control parameters configured by the network-side device for the uplink channel resources may include one or more groups of power control parameters, and each group of power control parameters includes one or more power control parameters. The power control parameters configured by the network-side device for the uplink channel resources may also include one or more sets of power control parameters, and each set of power control parameters includes one or more power control parameters. Multiple sets of power control parameters can also be divided into different groups, and each group of power control parameter sets includes one or more sets of power control parameters.

[0189] For example, assume that the network-side device configures A power control parameters and / or B sets of power control parameters for the uplink channel resource, where both A and B are integers greater than or equal to 1. The network-side device can indicate one or more power control parameters from the A power control parameters and / or the power control parameters included in the B sets of power control parameters through the indication information of the power control parameters to determine the transmission power of the uplink channel resource. Alternatively, the network-side device can also indicate one or more sets of power control parameters from the B sets of power control parameters through the indication information of the sets of power control parameters to determine the transmission power of the uplink channel resource.

[0190] Optionally, the indication information of the set of power control parameters can indicate one or more sets of power control parameters through at least one of the following: the identification information of the set of power control parameters, the number of sets of power control parameters, the group of sets of power control parameters, but not limited to this.

[0191] At this time, the indication information of the set of power control parameters can indicate one or more sets of power control parameters in various ways such as the identification information, number, and group of the set of power control parameters, and the indication method is flexible and changeable.

[0192] Step 102: Send the first target signaling to the terminal so that the terminal determines the transmission power of the uplink channel resource according to the first target signaling.

[0193] Here, the first target signaling is sent to the terminal, and the terminal determines the transmission power of the uplink channel resource according to the information for determining the transmission power of the uplink channel resource indicated by the first target signaling, so that the network-side device and the terminal can have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of M-TRP.

[0194] In the uplink channel power control method of the embodiments of the present application, the network-side device dynamically indicates the information for determining the transmission power of the uplink channel resource through the first target signaling. When the network-side device does not configure the spatial setting signaling for the terminal, the network-side device and the terminal can also have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of M-TRP. Moreover, the network-side device can indicate through various ways such as the identification information, number, group of the power control parameters, and the indication information of the set of power control parameters, and the indication method is flexible and changeable, with strong operability.

[0195] The uplink channel resources referred to in the embodiments of the present application include but are not limited to PUCCH (Physical Uplink Control Channel) resources and PUSCH (Physical Uplink Share Channel) resources.

[0196] Optionally, the first target signaling is a Media Access Control Control Element (MAC-CE) signaling or Downlink Control Information (DCI), but is not limited thereto.

[0197] At this time, the network device can indicate the power control parameter and / or the set of power control parameters of the uplink channel resources triggered by the DCI to the terminal through the MAC-CE or DCI. The terminal receives the DCI, determines that it needs to transmit the uplink channel resources, and determines the transmission power of the uplink channel resources according to the power control parameter and / or the set of power control parameters indicated by the MAC-CE or DCI. The network device does not configure the spatial setting signaling for the terminal, and the network device and the terminal can also have a consistent understanding of the transmission power of the uplink channel resources, ensuring the normal operation of the uplink channel transmission of the M-TRP.

[0198] In the embodiments of the present application, the network device can indicate one or more power control parameters by at least one of the identification information (such as ID) of the power control parameter, the number of power control parameters, and the group of power control parameters. Similarly, the network device can indicate one or more sets of power control parameters by at least one of the identification information of the set of power control parameters, the number of sets of power control parameters, and the group of power control parameters. The following describes these several indication methods as follows.

[0199] Method 1.1: Indicate the identification information of the power control parameter.

[0200] Optionally, the information for determining the transmission power of the uplink channel resources indicated by the first target signaling includes the indication information of the power control parameter. The indication information of the power control parameter indicates one or more power control parameters through the identification information of the power control parameter. The terminal determines the transmission power of the uplink channel resources according to the power control parameters corresponding to the multiple identification information indicated by the first target signaling.

[0201] For example, if the first target signaling (MAC-CE or DCI) indicates the power control parameter with ID 1 and the power control parameter with ID 2, the terminal determines the transmission power of the uplink channel resources according to these two power control parameters.

[0202] Method 1.2: Indicate the identification information of the set of power control parameters.

[0203] Optionally, the information for determining the transmission power of the uplink channel resources indicated by the first target signaling includes the indication information of the set of power control parameters. The indication information of the set of power control parameters indicates one or more sets of power control parameters through the identification information of the set of power control parameters. The terminal determines the transmission power of the uplink channel resources according to the power control parameters in the one or more sets of power control parameters corresponding to the identification information indicated by the first target signaling.

[0204] For example, if the first target signaling (MAC-CE or DCI) indicates the power control parameter set with ID 1 and the power control parameter set with ID 2, the terminal determines the transmission power of the uplink channel resource according to the power control parameters in these two power control parameter sets.

[0205] Wherein, when the network side device indicates one or more power control parameter sets, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in this one or more power control parameter sets, or can also select some power control parameters (such as the power control parameter with the smallest ID or the default power control parameter) according to the set rules in this one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0206] Method 1.3: Indicating the number of power control parameters.

[0207] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameters. The indication information of the power control parameters indicates one or more power control parameters through the number of power control parameters, and the number of power control parameters for determining the transmission power of the uplink channel resource is equal to the number indicated by the indication information of the power control parameters.

[0208] At this time, based on the number of power control parameters indicated by the first target signaling, the terminal determines the number of power control parameters used for determining the transmission power of the uplink channel resource. The terminal can select the corresponding number of power control parameters from the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0209] Wherein, when the network side device indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters according to the set rules (such as the power control parameter with the smallest ID or the default power control parameter) to determine the transmission power of the uplink channel resource

[0210] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal determines that the number of power control parameters used for determining the transmission power of the uplink channel resource is 1, and the terminal selects 1 power control parameter from the power control parameter configuration of the uplink channel resource according to the set rules to determine the transmission power of the uplink channel resource.

[0211] For another example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal determines that the number of power control parameters used for determining the transmission power of the uplink channel resource is 2, and the terminal selects 2 power control parameters from the power control parameter configuration of the uplink channel resource according to the set rules to determine the transmission power of the uplink channel resource.

[0212] Method 1.4: Indicating the number of power control parameter sets.

[0213] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes indication information of a set of power control parameters. The indication information of the set of power control parameters indicates one or more sets of power control parameters by the number of sets of power control parameters, and the number of sets of power control parameters for determining the transmission power of the uplink channel resource is equal to the number indicated by the indication information of the set of power control parameters.

[0214] At this time, the terminal determines the number of sets of power control parameters used for the transmission power of the uplink channel resource according to the number of sets of power control parameters indicated by the first target signaling. The terminal can select the corresponding number of sets of power control parameters from the power control parameter configuration of the uplink channel resource, and determine the transmission power of the uplink channel resource based on the power control parameters in the set of power control parameters.

[0215] Among them, when the network side indicates the number of sets of power control parameters, the terminal can select the corresponding number of sets of power control parameters according to the set rules (such as the power control parameter with the smallest ID or the default power control parameter). After the terminal selects the corresponding number of sets of power control parameters, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in the corresponding number of sets of power control parameters, or can also select some power control parameters (such as the power control parameter with the smallest ID or the default power control parameter) according to the set rules in the corresponding number of sets of power control parameters to determine the transmission power of the uplink channel resource.

[0216] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of sets of power control parameters is 1, the terminal determines that the number of sets of power control parameters used for the transmission power of the uplink channel resource is 1. The terminal selects 1 set of power control parameters from the power control parameter configuration of the uplink channel resource according to the set rules, and determines the transmission power of the uplink channel resource based on the power control parameters in the selected 1 set of power control parameters.

[0217] Method 1.5: Indicating the group of power control parameters.

[0218] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes indication information of power control parameters. The indication information of the power control parameters indicates one or more groups of power control parameters by the group of power control parameters, and the power control parameters for determining the transmission power of the uplink channel resource are the power control parameters in the group indicated by the indication information of the power control parameters.

[0219] At this time, the terminal determines the power control parameters used for the transmission power of the uplink channel resource among the power control parameters in the group indicated by the first target signaling. The terminal can select one or more power control parameters from the power control parameters in the indicated group to determine the transmission power of the uplink channel resource.

[0220] Among them, the network-side device indicates the group of power control parameters, and the terminal can select power control parameters from the power control parameters of the specified group according to the set rules (such as the power control parameters with the smallest ID or the default power control parameters), and determine the transmission power of the uplink channel resource.

[0221] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters, the terminal determines the power control parameters used for the transmission power of the uplink channel resource among the first group of power control parameters. The terminal can select one or more power control parameters from the first group of power control parameters according to the set rules to determine the transmission power of the uplink channel resource.

[0222] For another example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters and the second group of power control parameters, the terminal determines the power control parameters used for the transmission power of the uplink channel resource among the first group of power control parameters and the second group of power control parameters. The terminal can select one or more power control parameters from the first group of power control parameters and the second group of power control parameters respectively according to the set rules to determine the transmission power of the uplink channel resource.

[0223] Method 1.6: Indicating the group of power control parameter sets.

[0224] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter set. The indication information of the power control parameter set indicates one or more power control parameter sets through the group of the power control parameter set. The power control parameter set used for determining the transmission power of the uplink channel resource is the power control parameter set in the power control parameter sets of the group indicated by the indication information of the power control parameter set.

[0225] At this time, the terminal determines the power control parameter set used for the transmission power of the uplink channel resource in the power control parameter sets of the group indicated by the first target signaling. Optionally, the terminal selects one or more power control parameter sets from the power control parameter sets of the indicated group, and determines the transmission power of the uplink channel resource based on the power control parameters in the selected power control parameter sets. Optionally, the terminal uses all the power control parameter sets of the groups indicated by the first target signaling to determine the transmission power of the uplink channel resource.

[0226] Optionally, the network-side device indicates the group of power control parameter sets, and the terminal can select one or more power control parameter sets from the power control parameter sets of the specified group according to the set rules. After the terminal selects one or more power control parameter sets, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in these one or more power control parameter sets, or can also select some power control parameters (such as the power control parameters with the smallest ID or the default power control parameters) according to the set rules in these one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0227] For example, if the first target signaling (MAC-CE or DCI) indicates the first set of power control parameter sets, the terminal determines, from the first set of power control parameter sets, the power control parameter set used for the transmission power of the uplink channel resource. The terminal may select one or more power control parameter sets from the first set of power control parameter sets according to a set rule, and determine the transmission power of the uplink channel resource based on the power control parameters in the selected power control parameter sets.

[0228] In the above manners 1.2 to 1.6, when the first target signaling indicates the number of power control parameters, the group, or the identification information, number, and group of the power control parameter sets, the terminal may select some power control parameters or power control parameter sets according to a certain method. For the method of selecting some power control parameters or power control parameter sets, please refer to the following introduction.

[0229] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameters. The above step 101 includes any one of the following:

[0230] Optionally, the one or more power control parameters are the default power control parameters in the power control parameter configuration of the uplink channel resource.

[0231] Step 1011: Indicate one or more power control parameters from the default power control parameters in the power control parameter configuration of the uplink channel resource through the first target signaling.

[0232] Optionally, when the first target signaling indicates the identification information of the power control parameters, the first target signaling may indicate the identification information of one or more power control parameters from the default power control parameters in the power control parameter configuration of the uplink channel resource. The terminal uses the default power control parameters corresponding to the indicated identification information to determine the transmission power of the uplink channel resource.

[0233] Optionally, when the first target signaling indicates the number of power control parameters, the terminal may select the corresponding number of default power control parameters from the default power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0234] Among them, if the number of power control parameters indicated by the first target signaling is less than the number of default power control parameters included in the power control parameter configuration of the uplink channel resource, it may be agreed in the protocol that the smaller one is preferred.

[0235] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal selects 1 default power control parameter with the smallest identification from the default power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0236] Among them, if the number of power control parameters indicated by the first target signaling is greater than the number of default power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more default power control parameters, or add other specific power control parameters (such as identifying the smallest power control parameter or the power control parameter with a specific value).

[0237] Optionally, when the first target signaling indicates a group of power control parameters, the terminal can select one or more default power control parameters from the default power control parameters of the power control parameters indicating the group to determine the transmission power of the uplink channel resource.

[0238] Among them, if the number of default power control parameters included in the power control parameters indicating the group by the first target signaling is greater than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the smaller one is preferred.

[0239] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters, the terminal selects 2 default power control parameters with smaller identifiers from the default power control parameters in the first group of power control parameters to determine the transmission power of the uplink channel resource.

[0240] Among them, if the number of default power control parameters included in the power control parameters indicating the group by the first target signaling is less than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more default power control parameters, or add other specific power control parameters (such as identifying the smallest power control parameter or the power control parameter with a specific value).

[0241] Among them, the default power control parameters can be configured by the network side or agreed by the protocol.

[0242] Among them, the default power control parameter can be the power control parameter with the smallest identifier, but is not limited to this.

[0243] Optionally, the one or more power control parameters are the power control parameters among the first N or last N power control parameters in the power control parameter configuration of the uplink channel resource.

[0244] Step 1012: Indicate one or more power control parameters from the first N or last N power control parameters in the power control parameter configuration of the uplink channel resource through the first target signaling; N is an integer greater than or equal to 1; the power control parameters are sorted according to the identifier size or the configuration order.

[0245] Optionally, when the first target signaling indicates the identification information of the power control parameter, the first target signaling indicates the identification information of one or more power control parameters from the first N or last N power control parameters in the power control parameter configuration of the uplink channel resource, and the terminal uses the power control parameter corresponding to the indicated identification information to determine the transmission power of the uplink channel resource.

[0246] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters from the first N or last N power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0247] Among them, if the number of power control parameters indicated by the first target signaling is less than N, it can be agreed in the protocol that the power control parameter with a smaller identification or the default power control parameter is preferred.

[0248] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal selects the power control parameter with the smallest identification ranked first from the first 2 power control parameters in the power control parameter configuration of the uplink channel resource (N is equal to 2, and the power control parameters are sorted in ascending order of identification) to determine the transmission power of the uplink channel resource.

[0249] Among them, if the number of power control parameters indicated by the first target signaling is greater than N, it can be agreed in the protocol to multiplex one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identification or the power control parameter with an identification value of a specific value).

[0250] Optionally, when the first target signaling indicates the group of power control parameters, the terminal can select one or more power control parameters from the first N or last N power control parameters in the power control parameters of the indicated group to determine the transmission power of the uplink channel resource.

[0251] Among them, when the first target signaling indicates the group of power control parameters, if N is greater than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the power control parameter with a smaller identification or the default power control parameter is preferred.

[0252] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters, the terminal selects the power control parameter with a smaller identification ranked first in the first 2 power control parameters in the first group of power control parameters (N is equal to 2, and the power control parameters are sorted in ascending order of identification) to determine the transmission power of the uplink channel resource.

[0253] Among them, when the first target signaling indicates the group of power control parameters, if N is less than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to multiplex one or more power control parameters, or add other specific power control parameters (such as identifying the smallest power control parameter or the power control parameter with a specific value).

[0254] Optionally, the one or more power control parameters are the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource.

[0255] Step 1013: Indicate one or more power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration through the first target signaling.

[0256] Optionally, when the first target signaling indicates the identification information of the power control parameter, the first target signaling indicates the identification information of one or more power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameter corresponding to the indicated identification information to determine the transmission power of the uplink channel resource.

[0257] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of default power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0258] Among them, if the number of power control parameters indicated by the first target signaling is less than the number of default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the smaller power control parameters are preferred.

[0259] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal selects 2 smaller default power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0260] Among them, if the number of power control parameters indicated by the first target signaling is greater than the number of default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to multiplex one or more power control parameters, or add other specific power control parameters (such as identifying the smallest power control parameter or the power control parameter with a specific value).

[0261] Optionally, the one or more power control parameters are the power control parameters among the first M or last M power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource.

[0262] Step 1014: Indicate one or more power control parameters from the power control parameter sets ranked in the first M positions or the last M positions among the power control parameters included in the power control parameter configuration of the uplink channel resource through the first target signaling; M is an integer greater than or equal to 1; the power control parameters are sorted according to the identification size or the configuration order.

[0263] Optionally, when the first target signaling indicates the identification information of the power control parameter, the first target signaling indicates the identification information of one or more power control parameters from the power control parameter sets ranked in the first M positions or the last M positions among the power control parameters included in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameters corresponding to the indicated identification information to determine the transmission power of the uplink channel resource.

[0264] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters from the power control parameter sets ranked in the first M positions or the last M positions among the power control parameters included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0265] Among them, if the number of power control parameters indicated by the first target signaling is less than M, it can be agreed in the protocol that the power control parameter with a smaller identification or the default power control parameter is preferred.

[0266] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal selects the power control parameters with smaller identifications ranked in the first 2 positions from the power control parameter sets ranked in the first 4 positions among the power control parameters included in the power control parameter configuration of the uplink channel resource (M is equal to 4, and the power control parameters are sorted in ascending order of identification) to determine the transmission power of the uplink channel resource.

[0267] Among them, if the number of power control parameters indicated by the first target signaling is greater than M, it can be agreed in the protocol to reuse one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identification or the power control parameter with an identification value of a specific value).

[0268] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter set, and the above step 101 includes any one of the following:

[0269] Step 1015: Indicate one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource through the first target signaling, and the default power control parameter in the power control parameter set indicated by the first target signaling is the power control parameter for determining the transmission power of the uplink channel resource.

[0270] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling may indicate the identification information of one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource. The terminal uses the default power control parameters in the indicated one or more power control parameter sets to determine the power control parameters of the transmission power of the uplink channel resource.

[0271] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal may select the corresponding number of power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource. The default power control parameters in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0272] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the smaller power control parameter set or the default power control parameter set is marked as preferred.

[0273] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identification from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and uses the default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0274] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identification or the power control parameter set with the identification value being a specific value).

[0275] Optionally, when the first target signaling indicates the group of power control parameter sets, the terminal selects one or more power control parameter sets from the power control parameter sets of the indicated group, and uses the default power control parameters in the one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0276] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the power control parameter set of the indicated group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the smaller power control parameter set or the default power control parameter set is marked as preferred.

[0277] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects the power control parameter set with the smallest identification in the first group of power control parameter sets, and uses one or more default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0278] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as identifying the smallest power control parameter set or the power control parameter set with a specific value).

[0279] Among them, the default power control parameter set can be configured by the network side device, or can be agreed by the protocol.

[0280] Among them, the default power control parameter set can be the one identifying the smallest power control parameter set, but is not limited thereto.

[0281] Step 1016: Indicate one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource through the first target signaling, and the power control parameters ranked in the first P positions or the last P positions in the power control parameter sets indicated by the first target signaling are the power control parameters used to determine the transmission power of the uplink channel resource; P is an integer greater than or equal to 1; the power control parameters are sorted according to the identification size or the configuration order.

[0282] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling can indicate the identification information of one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and the terminal uses the power control parameters ranked in the first P positions or the last P positions in the indicated one or more power control parameter sets to determine the power control parameters of the transmission power of the uplink channel resource.

[0283] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal can select the corresponding number of power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and the power control parameters ranked in the first P positions or the last P positions in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0284] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the power control parameter set with a smaller identification or the default power control parameter set is preferred.

[0285] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identifier from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and uses the 2 power control parameters with the smallest identifiers in this 1 power control parameter set (P = 2, and the power control parameters are sorted in ascending order of identifiers) to determine the transmission power of the uplink channel resource.

[0286] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0287] Optionally, when the first target signaling indicates the group of power control parameter sets, the terminal can select one or more power control parameter sets from the power control parameter sets indicating the group, and the first P or last P power control parameters in this one or more power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0288] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the power control parameter set with the smallest identifier or the default power control parameter set is preferred.

[0289] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects the power control parameter set with the smallest identifier in the first group of power control parameter sets, and uses the first power control parameter with the smallest identifier in this 1 power control parameter set (P = 1, and the power control parameters are sorted in ascending order of identifiers) to determine the transmission power of the uplink channel resource.

[0290] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0291] Step 1017: Indicate one or more power control parameter sets from the default power control parameter sets in the power control parameter configuration of the uplink channel resource through the first target signaling, and the default power control parameters in the power control parameter sets indicated by the first target signaling are the power control parameters used to determine the transmission power of the uplink channel resource.

[0292] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling may indicate the identification information of one or more power control parameter sets from the power control parameter configurations of the uplink channel resources including the default power control parameter sets, and the terminal uses the default power control parameters in the corresponding one or more power control parameter sets of the identification information to determine the power control parameters of the transmission power of the uplink channel resources.

[0293] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal selects the corresponding number of power control parameter sets from the default power control parameter sets included in the power control parameter configuration of the uplink channel resources, and the default power control parameters in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resources.

[0294] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of default power control parameter sets included in the power control parameter configuration of the uplink channel resources, it can be agreed in the protocol that the smaller power control parameter set is marked as preferred.

[0295] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest default identification from the default power control parameter sets included in the power control parameter configuration of the uplink channel resources, and uses the default power control parameters in this 1 default power control parameter set to determine the transmission power of the uplink channel resources.

[0296] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resources, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identification or the power control parameter set with the identification value being a specific value).

[0297] Optionally, when the first target signaling indicates the group of the power control parameter sets, the terminal may select one or more power control parameter sets from the default power control parameter sets of the indicated group, and the default power control parameters in the one or more power control parameter sets are used to determine the transmission power of the uplink channel resources.

[0298] Among them, when the first target signaling indicates the group of the power control parameter sets, if the number of default power control parameter sets included in the power control parameter set of the indicated group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resources, it can be agreed in the protocol that the smaller power control parameter set is marked as preferred.

[0299] For example, if the first target signaling (MAC-CE or DCI) indicates the first set of power control parameter sets, the terminal selects, from the default power control parameter sets in the first set of power control parameter sets, the top 2 default power control parameter sets sorted in ascending order of the identifier, and uses the default power control parameters in these 2 power control parameter sets to determine the transmission power of the uplink channel resource.

[0300] Among them, when the first target signaling indicates the group of the power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with the identifier value being a specific value).

[0301] Step 1018: Indicate one or more power control parameter sets from the power control parameter sets ranked in the top Q or the last Q positions in the power control parameter configuration of the uplink channel resource through the first target signaling, and the default power control parameters in the power control parameter sets indicated by the first target signaling are the power control parameters used to determine the transmission power of the uplink channel resource; Q is an integer greater than or equal to 1; the power control parameter sets are sorted in ascending order of the identifier or in the configuration order.

[0302] Optionally, when the first target signaling indicates the identifier information of the power control parameter set, the first target signaling can indicate the identifier information of one or more power control parameter sets from the power control parameter sets ranked in the top Q or the last Q positions in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameters in the one or more power control parameter sets corresponding to the identifier information to determine the power control parameters of the transmission power of the uplink channel resource.

[0303] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal can select the corresponding number of power control parameter sets from the power control parameter sets ranked in the top Q or the last Q positions in the power control parameter configuration of the uplink channel resource, and the default power control parameters in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0304] Among them, if the number of power control parameter sets indicated by the first target signaling is less than Q, it can be agreed in the protocol that the power control parameter set with a smaller identifier or the default power control parameter set is preferred.

[0305] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identifier from the top 4 power control parameter sets (Q = 4, and the power control parameter sets are sorted in ascending order of the identifier) in the power control parameter configuration of the uplink channel resource, and uses the default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0306] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than Q, it can be agreed in the protocol to multiplex one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0307] Optionally, when the first target signaling indicates the group of power control parameter sets, the terminal can select one or more power control parameter sets from the top Q or bottom Q power control parameter sets in the indicated group of power control parameter sets, and the default power control parameters in this one or more power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0308] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the indicated group of power control parameter sets is greater than Q, it can be agreed in the protocol that the power control parameter set with a smaller identifier or the default power control parameter set is preferred.

[0309] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects 1 power control parameter set with the smallest identifier from the top 2 power control parameter sets (Q = 2, and the power control parameter sets are sorted in ascending order of the identifier) in the first group of power control parameter sets, and uses the default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0310] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the indicated group of power control parameter sets is less than Q, it can be agreed in the protocol to multiplex one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0311] The embodiments of the present application can flexibly indicate the power control parameters or power control parameter sets used to determine the transmission power of the uplink channel resource in the above multiple ways.

[0312] In the embodiments of the present application, when determining the transmission power of the uplink channel resources of M-TRP, it is also necessary to give the correspondence between the uplink channel resource repetition copies and the power control parameters or the set of power control parameters. This correspondence can be indicated by the network-side device or agreed upon by the protocol. The following introduces how to give the correspondence between the uplink channel resource repetition copies and the power control parameters or the set of power control parameters.

[0313] Optionally, the power control parameter for determining the transmission power of the first repetition copy of the uplink channel resource is the first power control parameter, and the first power control parameter is a power control parameter determined based on a first preset index.

[0314] Here, the terminal can determine the first power control parameter based on the first preset index and use the first power control parameter to determine the transmission power of the first repetition copy repetition of the uplink channel resource.

[0315] When agreeing upon the correspondence between the uplink channel resource repetition copies and the power control parameters or the set of power control parameters by the protocol, it can be agreed that the terminal determines the first power control parameter based on the first preset index. When the network-side device indicates the correspondence between the uplink channel resource repetition copies and the power control parameters or the set of power control parameters, if the network-side device indicates the correspondence between the group of power control parameters and the uplink channel resource repetition copies, or the network-side device indicates the identification information, group, and the correspondence between the set of power control parameters and the uplink channel resource repetition copies, it can also be agreed that the terminal determines the first power control parameter based on the first preset index. The following introduces them separately.

[0316] When giving the correspondence between the uplink channel resource repetition copies and the power control parameters or the set of power control parameters by the way of protocol agreement, it includes but is not limited to the following agreement methods:

[0317] Method 2.1: If the network-side device indicates the identification information of the power control parameters through the first target signaling, it can be agreed that the terminal determines the first power control parameter from the power control parameters corresponding to the identification information based on the first preset index.

[0318] Method 2.2: If the network-side device indicates the number of power control parameters through the first target signaling, after the terminal selects the corresponding number of power control parameters in the foregoing manner, it can be agreed that the terminal determines the first power control parameter from the corresponding number of power control parameters based on the first preset index.

[0319] Method 2.3: If the network-side device indicates a group of power control parameters through the first target signaling, it can be agreed that the terminal determines the first power control parameter from the indicated group of power control parameters based on the first preset index.

[0320] Method 2.4: If the network device indicates multiple sets of power control parameters through the first target signaling, it can be agreed that the terminal selects one set of power control parameters from the indicated multiple sets of power control parameters based on the first preset metric, and determines the first power control parameter from the selected set of power control parameters based on the first preset metric. The first preset metric used twice can be the same or different metrics.

[0321] Method 2.5: If the network device indicates the identification information of a power control parameter set through the first target signaling, it can be agreed through the protocol that the terminal selects one or more power control parameters from this power control parameter set based on the first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in this power control parameter set as the first power control parameter.

[0322] Method 2.6: If the network device indicates the identification information of multiple power control parameter sets through the first target signaling, it can be agreed through the protocol that the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metric used twice can be the same or different metrics; or it is agreed that after the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, it uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0323] Method 2.7: If the network device indicates that the number of power control parameter sets is 1 through the first target signaling, after the terminal selects one power control parameter set in the foregoing manner, it can be agreed through the protocol that the terminal selects one or more power control parameters from this power control parameter set based on the first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in this power control parameter set as the first power control parameter.

[0324] Method 2.8: If the network device indicates that the number of power control parameter sets is multiple through the first target signaling, after the terminal selects multiple power control parameter sets in the foregoing manner, it can be agreed through the protocol that the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metric used twice can be the same or different metrics; or it is agreed that after the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, it uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0325] Method 2.9: If the network device indicates a set of power control parameter sets through a first target signaling, through protocol agreement, the terminal selects one or more power control parameter sets from this set of power control parameter sets based on a first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that the terminal selects one or more power control parameter sets from this set of power control parameter sets based on the first preset metric and uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0326] Method 2.10: If the network device indicates multiple sets of power control parameter sets through a first target signaling, through protocol agreement, the terminal selects one set of power control parameter sets from these multiple sets of power control parameter sets based on a first preset metric, then continues to select one or more power control parameter sets from this one set of power control parameter sets based on the first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used three times can be the same or different metrics; or it is agreed that the terminal selects one set of power control parameter sets from these multiple sets of power control parameter sets based on the first preset metric, then continues to select one or more power control parameter sets from this one set of power control parameter sets based on the first preset metric, and then uses all the power control parameters in this one or more power control parameter sets as the first power control parameter, where the first preset metrics used twice can be the same or different metrics.

[0327] When the network device indicates the correspondence between the uplink channel resource repetition copies and the power control parameters or power control parameter sets, it includes but is not limited to the following agreement methods:

[0328] Method 3.1: If the network device indicates the correspondence between the group of power control parameters and the first repetition copy of the uplink channel resource, after the terminal determines the power control parameters of the group corresponding to the first repetition copy according to the correspondence, through protocol agreement, the terminal selects one or more power control parameters from the power control parameters of the group corresponding to the first repetition copy based on a first preset metric as the first power control parameter.

[0329] Method 3.2: If the network device indicates the correspondence between the identification information of the power control parameter set and the first repetition copy of the uplink channel resource, after the terminal determines the power control parameter set corresponding to the first repetition copy according to the correspondence, through protocol agreement, the terminal selects one or more power control parameters from the power control parameter set corresponding to the first repetition copy based on a first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in the power control parameter set corresponding to the first repetition copy as the first power control parameter.

[0330] Method 3.3: If the network-side device indicates the correspondence between the group of power control parameter sets and the first repeated copy of the uplink channel resource, after the terminal determines the power control parameter set of the group corresponding to the first repeated copy according to the correspondence, through protocol agreement, the terminal can select one or more power control parameter sets from the power control parameter sets of the group corresponding to the first repeated copy based on the first preset metric, and continue to select one or more power control parameters from these one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that the terminal selects one or more power control parameter sets from the power control parameter sets of the group corresponding to the first repeated copy based on the first preset metric, and uses all the power control parameters in these one or more power control parameter sets as the first power control parameter.

[0331] In the embodiments of the present application, the first power control parameter corresponding to the first repeated copy of the uplink channel resource can be determined through the above multiple methods. Optionally, for other repeated copies of the uplink channel resource, the repeated copies belonging to the same group as the first repeated copy can use the same power control parameters as the first repeated copy; the repeated copies not belonging to the same group as the first repeated copy can use different power control parameters from the first repeated copy.

[0332] Among them, the first repeated copy of the uplink channel resource refers to the copy of the initial transmission of the uplink channel resource.

[0333] In the embodiments of the present application, the network-side device can indicate the correspondence between the power control parameters or power control parameter sets and the repeated copies of the uplink channel resource to the terminal through the first target signaling or the second target signaling. Optionally, the method further includes any one of the following:

[0334] Indicating the correspondence information between the identification information or group of the power control parameters and the repeated copies of the uplink channel resource through the second target signaling;

[0335] Indicating the correspondence information between the identification information or group of the power control parameter sets and the repeated copies of the uplink channel resource through the second target signaling;

[0336] The first target signaling includes the correspondence information indicating the identification information or group of the power control parameters and the repeated copies of the uplink channel resource;

[0337] The first target signaling includes the correspondence information indicating the identification information or group of the power control parameter sets and the repeated copies of the uplink channel resource;

[0338] Among them, the second target signaling is different from the first target signaling.

[0339] At this time, the network-side device may indicate, through a second target signaling, the power control parameter or the identification information or group of the power control parameter set, or the information on the correspondence relationship between the power control parameter or the identification information or group of the power control parameter set and the duplicate of the uplink channel resource. The network-side device may also carry, in a first target signaling, the information on the correspondence relationship between the power control parameter or the identification information or group of the power control parameter set and the duplicate of the uplink channel resource. The terminal determines the power control parameter corresponding to the duplicate of the uplink channel resource according to the information on the correspondence relationship between the power control parameter or the identification information or group of the power control parameter set indicated by the first target signaling or the second target signaling.

[0340] Among them, if the first target signaling or the second target signaling indicates the information on the correspondence relationship between the identification information of the power control parameter and the first duplicate of the uplink channel resource, the terminal may directly use the power control parameter identified by the first duplicate of the uplink channel resource as the first power control parameter to determine its transmission power. For other duplicates, the duplicates belonging to the same group as the first duplicate may use the same power control parameter as the first duplicate, and the duplicates not belonging to the same group as the first duplicate may use different power control parameters from the first duplicate.

[0341] For example, the network-side device indicates, through the first target signaling, the power control parameter with an identification (such as ID) value of 3 and the power control parameter with an ID value of 4, and indicates, through the first target signaling, the information on the correspondence relationship between the power control parameter with an ID value of 3 and the first duplicate of the uplink channel resource. The terminal uses the power control parameter with an ID value of 3 to determine the transmission power of the first duplicate and the duplicates belonging to the same group as the first duplicate, and the terminal uses the power control parameter with an ID value of 4 to determine the transmission power of the duplicates not belonging to the same group as the first duplicate.

[0342] Of course, the first target signaling or the second target signaling may also indicate the information on the correspondence relationship between the identification information of the power control parameter and multiple duplicates of the uplink channel resource. When the correspondence relationship of multiple duplicates is indicated, each duplicate uses the power control parameter in the power control parameter identified by itself to determine its transmission power.

[0343] When the first target signaling or the second target signaling indicates the information on the correspondence relationship between the group of the power control parameter, the identification information of the power control parameter set, or the group of the power control parameter set and the first duplicate of the uplink channel resource, the first power control parameter used by the first duplicate of the uplink channel resource may be determined based on the first preset index with reference to the above methods 3.1 - 3.3.

[0344] Of course, the first target signaling or the second target signaling may also simultaneously indicate the power control parameter group, the identification information of the power control parameter set, or the information on the correspondence between the group of the power control parameter set and multiple duplicate copies of the uplink channel resource. When the correspondence between multiple duplicate copies is indicated, each duplicate copy uses its corresponding power control parameter or power control parameter set, and determines its transmission power by referring to the above methods 3.1 - 3.3, which will not be elaborated here.

[0345] Among them, as described above, the first target signaling may be MAC-CE or DCI.

[0346] Among them, the second target signaling may be the downlink control information DCI, and the identification information or group of the power control parameter and the information on the correspondence with the duplicate copies of the uplink channel resource, or the identification information or group of the power control parameter set and the information on the correspondence with the duplicate copies of the uplink channel resource are indicated by the transmit power control (TPC) field of the DCI.

[0347] At this time, the network-side device indicates the identification information or group of the power control parameter and the information on the correspondence with the duplicate copies of the uplink channel resource, or the identification information or group of the power control parameter set and the information on the correspondence with the duplicate copies of the uplink channel resource through the TPC (Transmit Power Control) field in the DCI.

[0348] For example, the network-side device indicates through the MAC-CE that the number of power control parameter sets of the uplink channel resource is 1, and indicates through the TPC field in the DCI that the power control parameter set corresponding to the duplicate copies of the uplink channel resource (when not specifying a certain duplicate copy, it is default applicable to all duplicate copies) is the first power control parameter set (the first power control parameter set can be any one in the power control parameter set configuration of the uplink channel resource, or the first power control parameter set is the power control parameter set ranked first in the power control parameter set configuration of the uplink channel resource arranged according to the configured order). The terminal uses the power control parameters in the first power control parameter set to determine the transmission power of the duplicate copies of the uplink channel resource.

[0349] For another example, the network-side device indicates that the number of power control parameter sets for the uplink channel resources is 2 through MAC-CE, and indicates that the power control parameter set corresponding to the uplink channel resource duplicate copy (when not specifying a certain duplicate copy, it is default applicable to all duplicate copies) is the first power control parameter set through the TPC field in DCI (the first power control parameter set can be any one in the power control parameter set configuration of the uplink channel resources, or the first power control parameter set is the power control parameter set that is ranked first in the power control parameter set configuration of the uplink channel resources in the configured order). At this time, there is a difference between the number of power control parameter sets indicated by MAC-CE and the number of power control parameter sets indicated by the TPC field in DCI. The terminal can determine the open-loop power control parameters (P 0 , path loss reference signal, closed-loop power control parameters, etc.) of the uplink channel resources according to the two power control parameter sets, and adjust the closed-loop power control of the uplink channel resource duplicate copy corresponding to the first power control parameter set.

[0350] Next, the first preset index in the embodiments of the present application will be introduced.

[0351] Optionally, the first preset index includes but is not limited to: the default power control parameter, the value of the identifier of the power control parameter itself, the size of the identifier of the power control parameter, the sorting of the groups of the power control parameters, the information field of the first target signaling, the order of the power control parameters indicated by the first target signaling, and any item in the coding sequence corresponding to the power control parameters indicated by the first target signaling, and / or, the valid state of the power control parameters indicated by the first target signaling; and / or

[0352] The first preset index includes but is not limited to: the default power control parameter set, the value of the identifier of the power control parameter set itself, the size of the identifier of the power control parameter set, the sorting of the groups of the power control parameter sets, the order of the power control parameter sets indicated by the first target signaling, and any item in the coding sequence corresponding to the power control parameter sets indicated by the first target signaling, and / or, the valid state of the power control parameter sets indicated by the first target signaling.

[0353] Among them, the default power control parameter or power control parameter set can be configured by the network side or agreed by the protocol. The default power control parameter or power control parameter set can be the power control parameter or power control parameter set with the smallest identifier (such as ID).

[0354] At this time, the terminal can use the default power control parameter or power control parameter set as an index to select the first power control parameter.

[0355] For example, the network-side device indicates the first group of power control parameters through the first target signaling, and the terminal can select the default power control parameter in the first group of power control parameters as the first power control parameter used for the first duplicate copy.

[0356] Among them, the value of the identifier (such as ID) itself represents the defined value of the identifier, while the size of the identifier represents the size compared with other identifiers. For example, for the power control parameter with ID equal to 5, the value of the identifier itself is 5. Compared with the power control parameter with ID equal to 0, its identifier is larger, and compared with the power control parameter with ID equal to 7, its identifier is smaller.

[0357] Optionally, the first power control parameter includes any one of the following:

[0358] The first power control parameter is the power control parameter whose value of the identifier itself is the first preset value;

[0359] The first power control parameter is the power control parameter in the set of power control parameters whose value of the identifier itself is the second preset value;

[0360] The first power control parameter is the power control parameter whose identifier size is at the first preset level;

[0361] The first power control parameter is the power control parameter in the set of power control parameters whose identifier size is at the second preset level;

[0362] Among them, the identifier size being at the first preset level or the identifier size being at the second preset level includes any one of the following: the smallest identifier, the largest identifier, the identifier size being at the intermediate value, but not limited thereto.

[0363] Among them, the first preset value and the second preset value can be set according to requirements and can be any value.

[0364] At this time, through protocol agreement, the terminal can determine the first power control parameter used for the first repeated copy according to the value of the identifier itself (the power control parameter with the identifier value being the first preset value or the set of power control parameters with the identifier value being the second preset value) or the identifier size (the power control parameter or the set of power control parameters with the smallest, largest or intermediate identifier) among the power control parameters or the set of power control parameters indicated by the first target signaling.

[0365] For example, the network-side device indicates the power control parameters with ID equal to 1 and ID equal to 2 through the first target signaling. The terminal selects the one with the smallest ID based on the identifier size, that is, the power control parameter with ID equal to 1, as the first power control parameter used for the first repeated copy.

[0366] For another example, the network-side device indicates that the number of power control parameters is 2 through the first target signaling. The terminal selects 2 power control parameters through the foregoing method and then selects the power control parameter with the smallest ID from these 2 power control parameters based on the identifier size as the first power control parameter used for the first repeated copy.

[0367] For another example, the network-side device indicates a first set of power control parameters through a first target signaling. The first set of power control parameters includes multiple power control parameters. The terminal may select the power control parameter with the smallest ID in the first set of power control parameters based on the ID size as the first power control parameter used for the first duplicate copy.

[0368] For another example, the network-side device indicates the power control parameter sets with IDs 1 and 2 through a first target signaling. The terminal may use all the power control parameters in the power control parameter set with ID 1 as the first power control parameter used for the first duplicate copy, or the terminal may use the power control parameter with the smallest ID or the default power control parameter in the power control parameter set with ID 1 as the first power control parameter used for the first duplicate copy.

[0369] For another example, the network-side device indicates through a first target signaling that the number of power control parameter sets is 1. The terminal may use the power control parameters in the power control parameter set with the smallest ID as the first power control parameter used for the first duplicate copy.

[0370] For another example, the network-side device indicates a first set of power control parameter sets through a first target signaling. The terminal may use all the power control parameters or the default power control parameters in the power control parameter set with the smallest ID in the first set of power control parameter sets as the first power control parameter used for the first duplicate copy.

[0371] Optionally, the first target signaling includes one or more information fields for indicating power control parameters and / or power control parameter sets, and at least part of the information fields are provided with indication information for indicating whether the power control parameters and / or power control parameter sets corresponding to the information fields are valid.

[0372] For example, at least part of the information fields include 1 bit of indication information for indicating whether the power control parameters and / or power control parameter sets corresponding to this information field are valid. If the indication is valid, the power control parameters and / or power control parameter sets corresponding to the information field may be used to determine the transmission power of the uplink channel resource. If the indication is invalid, the power control parameters and / or power control parameter sets corresponding to the information field are not used to determine the transmission power of the uplink channel resource.

[0373] Among them, as described above, the first target signaling may be MAC-CE or DCI. Optionally, the MAC-CE is a MAC-CE signaling for indicating the spatial correlation information SpatialRelationInfo of the uplink channel resource, and the MAC-CE includes information on whether the spatial reference signal indicated by the spatial correlation information SpatialRelationInfo is invalid. The spatial reference signal is a reference signal for determining the spatial filter coefficient of the uplink channel resource. When indicating that the spatial reference signal indicated by SpatialRelationInfo is invalid, the terminal does not use the spatial reference signal indicated by SpatialRelationInfo to determine the spatial filter coefficient of the uplink channel resource.

[0374] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with a set of power control parameters or two sets of power control parameters.

[0375] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with a set of power control parameter sets or two sets of power control parameter sets.

[0376] Optionally, the first target signaling is DCI and includes 2 bits, which are used to indicate whether the uplink channel resource is associated with a set of power control parameters or two sets of power control parameters. When indicating that the uplink channel resource is associated with a set of power control parameters, it also indicates which set of power control parameters the first repeated copy is associated with.

[0377] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with a set of power control parameter sets or two sets of power control parameter sets. When indicating that the uplink channel resource is associated with a set of power control parameter sets, it also indicates which set of power control parameters the first repeated copy is associated with.

[0378] Optionally, the first power control parameter is the power control parameter indicated by the information field ranked at the first preset position according to the order of multiple information fields indicating the power control parameter in the first target signaling; or

[0379] The first power control parameter is the power control parameter in the power control parameter set indicated by the information field ranked at the second preset position according to the order of multiple information fields indicating the power control parameter set in the first target signaling;

[0380] Among them, the information field ranked at the first preset position or the information field ranked at the second preset position includes any one of the following: the first information field, the last information field, the information field ranked in the middle position, but not limited thereto.

[0381] For example, the network-side device indicates four power control parameters through four information fields. The terminal may select the power control parameter indicated by the first information field as the first power control parameter based on the order of the information fields; or the terminal may select the valid power control parameters according to the order of the information fields and the valid status of the power control parameters, and arrange the power control parameter indicated by the first information field in the order of the information fields.

[0382] Among them, the order of the power control parameter / power control parameter set indicated by the first target signaling represents the order of simultaneously indicating multiple power control parameters / power control parameter sets when the first target signaling indicates multiple power control parameters / power control parameter sets.

[0383] Optionally, the first power control parameter is the power control parameter ranked at the fifth preset position among the power control parameters indicated by the first target signaling; or

[0384] The first power control parameter is the power control parameter in the power control parameter set ranked at the sixth preset position among the power control parameter sets indicated by the first target signaling;

[0385] Among them, the fifth preset position or the sixth preset position includes any one of the following: the first position, the last position, the middle position, but not limited thereto.

[0386] For example, the first target signaling indicates the power control parameter with ID 1 and the power control parameter with ID 2. At the same time, the power control parameter with ID 1 is prior and the power control parameter with ID 2 is subsequent (or the power control parameter with ID 2 is prior and the power control parameter with ID 1 is subsequent). The terminal may use the power control parameter ranked first in the ID order as the first power control parameter; or the terminal may select the first valid power control parameter among the indicated power control parameters as the first power control parameter based on the order of the power control parameters and the valid status of the power control parameters.

[0387] Optionally, the first target signaling includes an information field for indicating a power control parameter and / or a power control parameter set, and the information field is greater than or equal to bits, where K is the number of power control parameters or power control parameter sets indicated by the first target signaling.

[0388] Optionally, the first target signaling includes an information field for indicating a power control parameter and / or a power control parameter set, and the information field simultaneously indicates the order of the power control parameter and / or the power control parameter set. The information field is greater than or equal to bits, where K is the number of power control parameters or power control parameter sets indicated by the first target signaling, representing the number of permutations and combinations of selecting k from K numbers.

[0389] Among them, the coding sequence corresponding to the power control parameter / power control parameter set indicated by the first target signaling represents the coding bit sequence of the power control parameter / power control parameter set indicated by the first target signaling. The terminal can use the power control parameter / power control parameter set corresponding to a specific bit to determine the first power control parameter.

[0390] Optionally, the first power control parameter is the power control parameter corresponding to the coding at the seventh preset position in the coding sequence corresponding to the power control parameter indicated by the first target signaling; or

[0391] The first power control parameter is the power control parameter corresponding to the coding at the eighth preset position in the coding sequence corresponding to the power control parameter set indicated by the first target signaling;

[0392] Among them, the seventh preset position or the eighth preset position includes any one of the following: the most significant bit (MSB), the least significant bit (LSB), but not limited thereto.

[0393] For example, in the coding sequence corresponding to the power control parameter set indicated by the first target signaling, the most significant bit corresponds to the power control parameter with ID 2, and the terminal can use it as the first power control parameter.

[0394] Among them, the effective state of the power control parameter / power control parameter set indicated by the first target signaling represents the effective state determined by the indication information set in the information field of the first target signaling for indicating whether the power control parameter and / or power control parameter set corresponding to the information field is effective, or the effective state directly indicated by the first target signaling. The effective state of the power control parameter / power control parameter set indicated by the first target signaling can be combined with any of the indicators mentioned above for judgment.

[0395] Optionally, the first power control parameter is the power control parameter ranked at the third preset position in the order of the effective power control parameters indicated by the first target signaling; or

[0396] The first power control parameter is the power control parameter in the power control parameter set ranked at the fourth preset position in the order of the effective power control parameter sets indicated by the first target signaling;

[0397] Among them, the ranking at the third preset position or the fourth preset position includes any one of the following: the first effective position, the last effective position, the effective position in the middle, but not limited thereto.

[0398] For example, the first target signaling indicates the power control parameters with IDs 1 and 2, and at the same time indicates that the power control parameter with ID 1 is invalid and the power control parameter with ID 2 is valid. The terminal can use the first valid power control parameter, that is, the power control parameter with ID 2, as the first power control parameter.

[0399] Among them, the sorting of the groups of power control parameters represents the sorting of multiple groups of power control parameters according to a specific rule (such as the size of the group number), and the sorting of the groups of power control parameter sets represents the sorting of multiple groups of power control parameter sets according to a specific rule (such as the size of the group number). The terminal can determine the first power control parameter based on the sorting of the groups of power control parameters or power control parameter sets and in combination with any of the foregoing indicators; or determine the first power control parameter only based on the sorting of the groups of power control parameters or power control parameter sets.

[0400] Optionally, the first power control parameter is the power control parameter in the group ranked at the ninth preset position according to the sorting of the groups of power control parameters in the multiple groups of power control parameter configurations of the uplink channel resources; or

[0401] The first power control parameter is the power control parameter in the power control parameter set in the group ranked at the tenth preset position according to the sorting of the groups of power control parameter sets in the multiple groups of power control parameter sets configured for the uplink channel resources;

[0402] Among them, the group at the ninth preset position or the group at the tenth preset position includes any one of the following: the first group, the last group, the group ranked in the middle position, but not limited thereto.

[0403] For example, the first target signaling indicates the first group of power control parameters and the second group of power control parameters. The terminal can select the first group of power control parameters based on the sorting of the groups of power control parameters, and select the power control parameter with the smallest identifier in the first group of power control parameters based on the identifier size as the first power control parameter used for the first duplicate copy.

[0404] In the embodiments of the present application, the terminal can determine the first power control parameter based on any one of the default power control parameter or power control parameter set, the value of the identifier of the power control parameter or power control parameter set itself, the identifier size, the information field of the first target signaling, the order of the power control parameter or power control parameter set indicated by the first target signaling, and the coding sequence corresponding to the power control parameter or power control parameter set indicated by the first target signaling, or determine the first power control parameter based on the valid state of the power control parameter or power control parameter set indicated by the first target signaling, or determine the first power control parameter based on the sorting of the groups of multiple power control parameters or power control parameter sets indicated by the first target signaling, or can also determine the first power control parameter based on the combination of multiple of the above parameters. The method is flexible and highly operable.

[0405] Optionally, the indication information of the power control parameter indicates multiple power control parameters, or the power control parameter set indicated by the indication information of the power control parameter set is a power control parameter set including multiple power control parameters, and the first preset metrics used for the first power control parameters corresponding to different types of power control parameters are the same or different.

[0406] At this time, if the first target signaling indicates multiple power control parameters, or indicates a power control parameter set including multiple power control parameters, the first power control parameters corresponding to different types of power control parameters can be determined using the same or different first preset metrics.

[0407] For example, the first target signaling indicates two reference signals, namely P 0 and path loss reference signal. For P 0 the power control parameter for the first repeated copy of the uplink channel resource can be determined using the identification size, and for the path loss reference signal, the power control parameter for the first repeated copy of the uplink channel resource can be determined using the value of the identification itself.

[0408] Optionally, the network side device uses other signaling to indicate the closed-loop power control parameter.

[0409] Optionally, the method further includes:

[0410] Configuring one or more sets of common power control parameters applicable to all dedicated uplink channel resources; or

[0411] Configuring one or more sets of common power control parameters applicable to all dedicated uplink channel resources, and configuring one or more sets of dedicated power control parameters dedicated to the uplink channel resources for the uplink channel resources.

[0412] Here, the network side device can configure one or more sets of power control parameters for the uplink channel resources through RRC signaling. One possible configuration method is that the network side device configures multiple sets of power control parameters in the dedicated uplink channel resource configuration, and the configured power control parameters are applicable to all dedicated uplink channel resources (dedicated uplink channel resources). Another possible configuration method is that the network side device configures 1 set of uplink channel resource power control parameters in the dedicated uplink channel resource configuration, and the configured power control parameters are applicable to all dedicated uplink channel resources (dedicated uplink channel resources), and the network side device configures one or more sets of power control parameters in the uplink channel resource configuration information, and the power control parameters are only applicable to the called uplink channel resources.

[0413] Optionally, when configuring one or more sets of common power control parameters and configuring one or more sets of dedicated power control parameters, step 101 above includes:

[0414] Indicate, from the public power control parameter and the dedicated power control parameter, information for determining the transmission power of the uplink channel resource through a first target signaling.

[0415] At this time, for an uplink channel resource, if the network side device does not configure dedicated power control parameters for it, the uplink channel resource uses the public power control parameter to determine its transmission power. For an uplink channel resource, if the network side device configures dedicated power control parameters for it, the uplink channel resource uses both the public power control parameter and the dedicated power control parameter to determine its transmission power.

[0416] Optionally, an uplink channel resource is configured with multiple repetition copies, and a part of the repetitions use the public power control parameter to determine the transmission power; the remaining repetitions use the dedicated power control parameter to determine the transmission power.

[0417] Optionally, each set of power control parameters configured by RRC signaling includes one or more power control parameters, and the power control parameter with the smallest ID in each set of power control parameters is the default power control parameter.

[0418] Optionally, the power control parameter includes at least one of the following: P 0 , path loss reference signal, closed-loop loop parameter (closeloopIndex).

[0419] Optionally, before sending the first target signaling to the terminal, the method further includes:

[0420] Carry the identifier of one or more uplink channel resources in the first target signaling, and the information for determining the transmission power of the uplink channel resource indicated in the first target signaling is applicable to any uplink channel resource with an identifier carried in the first target signaling.

[0421] At this time, the network side device can simultaneously indicate power control parameters or a set of power control parameters applicable to multiple uplink channel resources.

[0422] In addition to configuring power control parameters or a set of power control parameters for determining the transmission power of the uplink channel resource by using MAC-CE / DCI, optionally, the network side device can also independently indicate the association relationship between each uplink channel resource and the power control parameters or the set of power control parameters through RRC signaling. For example, indicate in the PUCCH-resource.

[0423] Optionally, before step 101 above, the method further includes:

[0424] Group the uplink channel resources of the terminal;

[0425] The above step 101 includes:

[0426] For any set of uplink channel resources, information for determining the transmission power of the uplink channel resources is indicated from the power control configuration pre-configured for the set of uplink channel resources through a first target signaling.

[0427] Here, the network-side device may divide the uplink channel resources into some groups, and for each group, respectively indicate the association relationship between the uplink channel resource group and the power control parameter or set of power control parameters, and the association relationship is applicable to all uplink channel resources within the uplink channel resource group. The specific manner may adopt the manner listed above, and replace "uplink channel resource group" therein with "uplink channel resource group".

[0428] The embodiments of the present application are applicable to PUCCH and PUSCH, but are not limited thereto.

[0429] Optionally, the uplink channel resource is a physical uplink shared channel (PUSCH) resource, and the first repeated copy is the earliest nominal repeated copy in terms of transmission time.

[0430] Here, when the PUSCH repeated copy type is Type B, the repeated copy is a nominal repeated copy.

[0431] Optionally, the uplink channel resource is a physical uplink control channel (PUCCH) resource, and the first repeated copy is the earliest actually transmitted repeated copy in terms of transmission time, or the first repeated copy is the earliest repeated copy opportunity.

[0432] Here, for the repetition opportunity of the uplink channel resource, if some repetition opportunities of the uplink channel resource cannot be transmitted due to conflict with the DL symbol, the repetition opportunity of the uplink channel resource is discarded.

[0433] Optionally, the embodiments of the present application can be used when the network-side device does not configure spatial-related information (i.e., PUCCH-SpatialRelationInfo) for the terminal but configures pathlossReferenceRS.

[0434] Optionally, when the network-side device does not configure pathlossReferenceRS for the terminal, the terminal can use the reference signal obtained through the SS / PBCH block with the same serial number as the SS / PBCH block for the terminal to obtain the MIB as the pathloss reference signal for all repetitions of the uplink channel resource.

[0435] Optionally, before the terminal is configured with power control parameters, the terminal uses the reference signal obtained from the SS / PBCH block that is the same as the SS / PBCH block serial number for the terminal to obtain the MIB as the path loss reference signal for all repetition copies of the uplink channel resources.

[0436] In the embodiments of the present application, there are slight differences between the terminal-specific uplink channel resources and the cell common uplink channel resources.

[0437] When the uplink channel resources are configured as terminal-specific uplink channel resources, the power control parameters may include P 0 , path loss reference signal parameters, and closed-loop loop parameters.

[0438] When the uplink channel resources are configured as cell common uplink channel resources, the power control parameters may include P 0 .

[0439] Taking PUCCH as an example below (similarly applicable to PUSCH), two specific application examples of the embodiments of the present application are illustrated as follows.

[0440] Application Example 1:

[0441] S1: The network-side device configures a set of power control parameters for the PUCCH resources through RRC signaling.

[0442] Here, a possible configuration method is that the base station configures a set of PUCCH power control parameters in the dedicated PUCCH configuration, and the configured power control parameters are applicable to all dedicated PUCCH resources. A set of PUCCH power control parameters may include one or more PUCCH power control parameters.

[0443] Optionally, the configured power control parameters include but are not limited to at least one of the following: P 0 , path loss reference signal, and closed-loop loop parameter (closeloopIndex). When there are multiple configured power control parameters, in this embodiment, these multiple power control parameters can be packaged into a power control parameter set.

[0444] Optionally, sorted by ID size, one or more power control parameters ranked in the front are default power control parameters. For example, the first 2 power control parameters with smaller DIs are default power control parameters.

[0445] S2: The network-side device indicates the power control parameters of the PUCCH resources to the terminal from the power control parameters configured by the RRC signaling through MAC-CE / DCI.

[0446] Optionally, the MAC-CE / DCI may indicate, from among multiple default power control parameters in the configured power control parameters, the power control parameter used to calculate the transmission power of the PUCCH resource.

[0447] Optionally, the MAC-CE / DCI sorts the configured power control parameters in ascending order of ID, and indicates, from among the one or more power control parameters ranked at the front, the power control parameter used to calculate the transmission power of the PUCCH resource.

[0448] Optionally, the MAC-CE / DCI may indicate multiple power control parameters through multiple information fields, and the first power control parameter is the power control parameter indicated by the first information field.

[0449] For example, the MAC-CE / DCI includes multiple information fields, and at least some of the information fields include 1 bit used to indicate whether the default power control parameter corresponding to this information field is valid. If it is indicated as valid, the power control parameter is used to determine the transmission power of the PUCCH; if it is indicated as invalid, the power control parameter is not used to determine the transmission power of the PUCCH. At this time, the first power control parameter may be the first valid power control parameter indicated by the MAC-CE.

[0450] Optionally, the MAC-CE is a MAC-CE signaling used to indicate the spatial related information SpatialRelationInfo of the PUCCH resource. The MAC-CE includes information indicating whether the spatial reference signal indicated by the SpatialRelationInfo is invalid. The spatial reference signal is a reference signal used to determine the spatial filter coefficient of the PUCCH resource. When it is indicated that the spatial reference signal indicated by the SpatialRelationInfo is invalid, the terminal does not use the spatial reference signal to determine the spatial filter coefficient of the PUCCH resource. Optionally, the MAC-CE includes multiple SpatialRelationInfo indication fields. At least some of the information fields include 1 bit used to indicate whether the power control parameter corresponding to this information field is valid. If it is indicated as valid, the power control parameter is used to determine the transmission power of the PUCCH; if it is indicated as invalid, the power control parameter is not used to determine the transmission power of the PUCCH. At this time, optionally, the first power control parameter is the first valid power control parameter indicated by the MAC-CE.

[0451] Optionally, the MAC-CE / DCI may indicate the power control parameter corresponding to the PUCCH resource by indicating the number of power control parameters corresponding to the PUCCH resource.

[0452] For example, if the MAC-CE / DCI indicates that the number of power control parameters corresponding to the PUCCH is 1, the terminal determines the transmission power of the PUCCH using the power control parameter with the smallest ID or a default power control parameter; if the MAC-CE / DCI indicates that the number of power control parameters corresponding to the PUCCH is 2, the terminal determines the transmission power of the PUCCH using the two power control parameters with the smallest IDs or two default power control parameters. Optionally, the first power control parameter is the power control parameter with the smallest ID.

[0453] For another example, if the MAC-CE / DCI indicates that the number of power control parameters corresponding to the PUCCH is 1, the terminal determines the transmission power of the PUCCH using the power control parameter with the smallest ID among the first set of power control parameters configured by RRC; if the MAC-CE / DCI indicates that the number of the power control parameters corresponding to the PUCCH is 2, the terminal determines the transmission power of the PUCCH using the power control parameters with the smallest IDs respectively among the two sets of power control parameters configured by RRC.

[0454] Optionally, the MAC-CE / DCI may include indication information on the correspondence between the PUCCH resource repetition copies and the power control parameters. For example, there is an information field in the MAC-CE to indicate the correspondence.

[0455] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters.

[0456] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets.

[0457] Optionally, the first target signaling is DCI and includes 2 bits, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters. When indicating that the uplink channel resource is associated with one set of power control parameters, it also indicates which set of power control parameters the first repetition copy is associated with.

[0458] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets. When indicating that the uplink channel resource is associated with one set of power control parameter sets, it also indicates which set of power control parameters the first repetition copy is associated with.

[0459] S3: The terminal receives the DCI and determines that a PUCCH needs to be transmitted.

[0460] S4: The terminal determines the transmission power of the PUCCH resource according to the power control parameters indicated by the MAC-CE / DCI, and uses the first power control parameter indicated by the MAC-CE / DCI to determine the transmission power of the first repetition copy of the PUCCH resource.

[0461] Optionally, when the MAC-CE / DCI indicates the IDs of multiple power control parameters, the terminal may determine the first power control parameter according to the order of the IDs. The terminal may also determine the first power control parameter according to the coding sequence corresponding to the information field indicating the power control parameter in the MAC-CE, or the terminal may determine the first power control parameter from the valid power control parameters indicated by the MAC-CE, or may determine the first power control parameter according to the ID of the power control parameter.

[0462] Application Example 2:

[0463] S1: The network device configures multiple sets of power control parameters for the PUCCH resource through RRC signaling.

[0464] Here, a possible configuration method is that the network device configures multiple sets of PUCCH power control parameters in the dedicated PUCCH configuration, and the configured power control parameters are applicable to all dedicated PUCCH resources.

[0465] Another possible configuration method is that the network device configures 1 set of PUCCH power control parameters in the dedicated PUCCH configuration, and the configured power control parameters are applicable to all dedicated PUCCH resources. The network device configures one or more sets of PUCCH power control parameters in the PUCCH resource configuration information, and the power control parameters are only applicable to this PUCCH resource.

[0466] Optionally, for a PUCCH resource, if the network device does not configure dedicated power control parameters for it, the PUCCH resource uses the common power control parameters to determine its transmission power; if the network device configures dedicated power control parameters for it, the PUCCH resource uses the common power control parameters and the dedicated power control parameters together to determine its transmission power. Optionally, a PUCCH resource is configured with multiple repetitions, and a part of the repetitions use the common power control parameters to determine the transmission power; the remaining repetitions use the dedicated power control parameters to determine the transmission power.

[0467] Optionally, a set of PUCCH power control parameters may include one or more PUCCH power control parameters.

[0468] Optionally, the configured power control parameters may include at least one of the following: P 0 , path loss reference signal, closed-loop loop parameter (closeloopIndex). When multiple power control parameters are configured, in this embodiment, these multiple power control parameters may be packaged into a power control parameter set.

[0469] Optionally, each set of power control parameters configured by RRC signaling includes one or more power control parameters, and the power control parameter with the smallest ID in each set of power control parameters is the default power control parameter.

[0470] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters.

[0471] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets.

[0472] Optionally, the first target signaling is DCI and includes 2 bits, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters. When indicating that the uplink channel resource is associated with one set of power control parameters, it also indicates which set of power control parameters the first repeated copy is associated with.

[0473] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets. When indicating that the uplink channel resource is associated with one set of power control parameter sets, it also indicates which set of power control parameters the first repeated copy is associated with.

[0474] S2: The network side device indicates the power control parameter of the PUCCH resource to the terminal from the power control parameters configured by RRC signaling through MAC-CE.

[0475] It includes all the solutions of Application Example 1. In addition, it also includes the following solutions:

[0476] Optionally, MAC-CE can indicate the group where the power control parameter used to calculate the transmission power of the PUCCH resource is located. The terminal determines the transmission power of the PUCCH using the power control parameter with the smallest ID in the group indicated by MAC-CE, and the first repeated copy of the PUCCH uses the power control parameter with the smallest ID in the first group to determine its transmission power.

[0477] Optionally, MAC-CE can also indicate the group where the power control parameter used to calculate the transmission power of the PUCCH resource is located. The terminal determines the transmission power of the PUCCH using the default power control parameter in the group indicated by MAC-CE, and the first repeated copy of the PUCCH uses the default power control parameter in the first group to determine its transmission power.

[0478] Optionally, MAC-CE can also indicate the power control parameter corresponding to the PUCCH resource by indicating the number of the power control parameters corresponding to the PUCCH resource.

[0479] For example, if the MAC-CE indicates that the number of power control parameters corresponding to the PUCCH is 1, the terminal determines the transmission power of the PUCCH using the power control parameter with the smallest ID in a preset group (such as the first group, or the power control parameter configured in the dedicated PUCCH parameters) or the default power control parameter; if the MAC-CE indicates that the number of power control parameters corresponding to the PUCCH is 2, the terminal determines the transmission power of the PUCCH / PUSCH using the power control parameter with the smallest ID in each of the two groups or the default power control parameter. Optionally, the first power control parameter is the power control parameter with the smallest ID.

[0480] For example, the information field of the MAC-CE indicating the power control parameter includes 2-bit information, and the power control parameter groups and power control parameters indicated by each state are shown in Table 1 or Table 2:

[0481] Table 1

[0482] Coding status Power control parameters corresponding to PUCCH resources 00 The first set of power control parameters 01 The second set of power control parameters 10 The first set and the second set of power control parameters 11 Reservation status

[0483] Table 2

[0484]

[0485] Optionally, the terminal jointly determines the transmission power of the PUCCH based on the P with the smallest ID within each group in the power control parameter group indicated by the MAC-CE signaling 0 , the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. Taking Table 1 as an example, if the state 00 is received, the terminal determines the transmission power of the PUCCH (or the transmission power of the first repetition of the PUCCH) according to the P with the smallest ID in the first group of power control parameters 0 , the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. If the terminal does not receive an indication of the spatial correlation parameters of the PUCCH resource, but receives the above MAC-CE, and the above MAC-CE signaling indicates 2 groups of power control parameters, the terminal jointly determines the transmission power of the PUCCH according to the P with the smallest ID in each of the two groups of power control parameters 0 , the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. Taking Table 1 as an example, if the state 10 is received, the terminal determines the transmission power of the first transmission copy of the PUCCH and the transmission copies in its group according to the P with the smallest ID in the first group of power control parameters 0 , the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. The terminal determines the transmission power of the other transmission copies of the PUCCH according to the P with the smallest ID in the second group of power control parameters 0 , the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0.

[0486] Optionally, the MAC-CE may include information indicating the correspondence between the first repeated copy of the PUCCH resource and the power control parameter group configured by RRC signaling.

[0487] Optionally, the MAC-CE may include information indicating the group of multiple power control parameter groups configured by the network-side device for the PUCCH resource through RRC signaling and the correspondence between the repeated transmission copies of the PUCCH resource and the multiple power control parameter groups. The two pieces of information may be independently indicated by two parameters or jointly indicated by the same parameter. For example, assume that the information field for indicating the power control parameters of the PUCCH resource in the MAC-CE is 2-bit information, and the power control parameter groups indicated by each state and the correspondence between the repeated transmission copies of the PUCCH resource and the multiple power control parameter groups are as shown in the following table:

[0488] Table 3

[0489]

[0490]

[0491] Optionally, the terminal may determine the transmission power of each repeated transmission copy of the PUCCH resource according to the power control parameters of the group corresponding to the MAC-CE group indication information and the correspondence between the repeated transmission copies of the PUCCH resource and the multiple power control parameter groups. In the example of Table 3, if status 10 is received, the terminal determines the transmission power of the transmission copy (e.g., pointing to TRP 1) of the first transmission copy group of the PUCCH resource according to the P with the smallest identifier (ID) in the first group of power control parameters, the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0, and determines the transmission power of the transmission copy (e.g., pointing to TRP 2) of the PUCCH resource that is not in the same group as the first transmission copy according to the P with the smallest identifier (ID) in the second group of power control parameters, the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. 0 and the transmission power of the transmission copy (e.g., pointing to TRP 1) of the first transmission copy group of the PUCCH resource is determined according to the P with the smallest identifier (ID) in the first group of power control parameters, the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0, and the transmission power of the transmission copy (e.g., pointing to TRP 2) of the PUCCH resource that is not in the same group as the first transmission copy is determined according to the P with the smallest identifier (ID) in the second group of power control parameters, the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0. 0 and the transmission power of the transmission copy (e.g., pointing to TRP 2) of the PUCCH resource that is not in the same group as the first transmission copy is determined according to the P with the smallest identifier (ID) in the second group of power control parameters, the path loss reference signal with the smallest ID, and the closed-loop loop numbered 0.

[0492] Optionally, if the MAC-CE signaling includes the identifiers of multiple PUCCH resources and one piece of power control parameter-related information (the information in the above table), the power control parameter-related information is applied to all the PUCCH resources indicated by the MAC-CE signaling.

[0493] In addition to configuring the association relationship of the power control parameters in the PUCCH resource domain using the MAC-CE, optionally, the network-side device independently indicates the association relationship between each PUCCH resource and the power control parameters through RRC signaling. For example, it is indicated in the PUCCH-resource.

[0494] Optionally, the network-side device may divide PUCCH resources into some groups, and for each group, respectively indicate the association relationship between the PUCCH resource group and the power control parameters, and the association relationship applies to all PUCCH resources within the PUCCH resource group. The specific method may adopt the methods listed above, and replace "PUCCH resource" with "PUCCH resource group".

[0495] S3: The terminal receives DCI and determines that PUCCH needs to be transmitted.

[0496] S4: The terminal determines the transmission power of the PUCCH resource according to the power control parameters indicated by the MAC-CE / DCI, and uses the first power control parameter indicated by the MAC-CE / DCI to determine the transmission power of the first repetition of the PUCCH resource.

[0497] The content is similar to Application Example 1.

[0498] It includes all the solutions of Application Example 1. In addition, it also includes the following solutions:

[0499] Optionally, when multiple groups of power control parameters are configured by RRC signaling, the terminal determines the first power control parameter according to the group of the power control parameters.

[0500] Application Example 3:

[0501] S1: The network-side device configures a set of power control parameter sets for the PUCCH resource through RRC signaling.

[0502] Here, a possible configuration method is that the base station configures a set of PUCCH power control parameter sets in the dedicated PUCCH configuration, and the configured power control parameter sets apply to all dedicated PUCCH resources. A set of PUCCH power control parameter sets may include one or more PUCCH power control parameters.

[0503] Optionally, the power control parameters in the configured power control parameter sets include but are not limited to at least one of the following: P 0 , path loss reference signal, closed-loop loop parameter (closeloopIndex).

[0504] Optionally, the power control parameter sets are sorted according to the ID size, and the one or more power control parameter sets ranked in the front are the default power control parameter sets.

[0505] Optionally, the power control parameters in the power control parameter sets are sorted according to the ID size, and the one or more power control parameters ranked in the front are the default power control parameters. For example, the first 2 power control parameters with smaller DIs are the default power control parameters.

[0506] S2: The network-side device indicates the power control parameter of the PUCCH resource to the terminal from the power control parameter set configured by the RRC signaling through MAC-CE / DCI, or the network-side device indicates the power control parameter set of the PUCCH resource to the terminal from the power control parameter set configured by the RRC signaling through MAC-CE / DCI.

[0507] Optionally, MAC-CE / DCI may indicate the power control parameter used to calculate the transmission power of the PUCCH resource from the default power control parameters in the power control parameter set included in the power control parameter configuration.

[0508] Optionally, MAC-CE / DCI sorts the power control parameters included in the power control parameter configuration according to the ID size, and among the multiple power control parameters ranked in the front, indicates the power control parameter used to calculate the transmission power of the PUCCH resource.

[0509] Optionally, MAC-CE / DCI indicates multiple power control parameters through multiple information fields from the power control parameter set included in the power control parameter configuration, and the first power control parameter is the power control parameter indicated by the first information field.

[0510] For example, MAC-CE / DCI includes multiple information fields, and at least some of the information fields include 1 bit to indicate whether the default power control parameter corresponding to this information field is valid. If it is indicated as valid, the power control parameter is used to determine the transmission power of the PUCCH; if it is indicated as invalid, the power control parameter is not used to determine the transmission power of the PUCCH. At this time, the first power control parameter may be the first valid power control parameter indicated by the MAC-CE.

[0511] Optionally, the MAC-CE is a MAC-CE signaling used to indicate the spatial-related information SpatialRelationInfo of the PUCCH resource. The MAC-CE includes information on whether the spatial reference signal indicated by the SpatialRelationInfo is invalid. The spatial reference signal is a reference signal used to determine the spatial filter coefficient of the PUCCH resource. When it is indicated that the spatial reference signal indicated by the SpatialRelationInfo is invalid, the terminal does not use the spatial reference signal to determine the spatial filter coefficient of the PUCCH resource. Optionally, the MAC-CE includes multiple SpatialRelationInfo indication fields. At least some of the information fields include 1 bit to indicate whether the power control parameter corresponding to this information field is valid. If it is indicated as valid, the power control parameter is used to determine the transmission power of the PUCCH; if it is indicated as invalid, the power control parameter is not used to determine the transmission power of the PUCCH. At this time, optionally, the first power control parameter is the first valid power control parameter indicated by the MAC-CE.

[0512] Optionally, the MAC-CE / DCI may indicate the power control parameter set corresponding to the PUCCH resource by indicating the number of power control parameter sets corresponding to the PUCCH resource.

[0513] For example, if the MAC-CE / DCI indicates that the number of power control parameter sets corresponding to the PUCCH is 1, the terminal uses the power control parameter with the smallest ID in the default power control parameter set or a default power control parameter to determine the transmission power of the PUCCH; if the MAC-CE / DCI indicates that the number of power control parameter sets corresponding to the PUCCH is 2, the terminal uses the power control parameter with the smallest ID in each of the two default power control parameter sets or a default power control parameter to determine the transmission power of the PUCCH. Optionally, the first power control parameter is the power control parameter with the smallest ID.

[0514] For another example, if the MAC-CE / DCI indicates that the number of power control parameter sets corresponding to the PUCCH is 1, the terminal uses the power control parameter with the smallest ID in the power control parameter set that is ranked first in the power control parameter sets configured by RRC in the configured order to determine the transmission power of the PUCCH; if the MAC-CE / DCI indicates that the number of the power control parameters corresponding to the PUCCH is 2, the terminal uses the power control parameter with the smallest ID in each of the first two power control parameter sets that are ranked in the configured order in the power control parameter sets configured by RRC to determine the transmission power of the PUCCH.

[0515] Optionally, the MAC-CE / DCI may include indication information on the correspondence between the PUCCH resource duplicate and the power control parameter set. For example, there is an information field in the MAC-CE to indicate the correspondence.

[0516] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters.

[0517] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets.

[0518] Optionally, the first target signaling is DCI and includes 2 bits, which is used to indicate whether the uplink channel resource is associated with one set of power control parameters or two sets of power control parameters. When indicating that the uplink channel resource is associated with one set of power control parameters, it also indicates which set of power control parameters the first duplicate is associated with.

[0519] Optionally, the first target signaling is DCI and includes 1 bit, which is used to indicate whether the uplink channel resource is associated with one set of power control parameter sets or two sets of power control parameter sets. When indicating that the uplink channel resource is associated with one set of power control parameter sets, it also indicates which set of power control parameters the first duplicate is associated with.

[0520] S3: The terminal receives DCI and determines that PUCCH needs to be transmitted.

[0521] S4: The terminal determines the transmission power of the PUCCH resource according to the power control parameter in the power control parameter set indicated by the MAC-CE / DCI, and uses the power control parameter with the smallest ID or the default power control parameter in the power control parameter set indicated by the MAC-CE / DCI to determine the transmission power of the first repetition of the PUCCH resource.

[0522] Optionally, when the MAC-CE / DCI indicates the IDs of multiple power control parameter sets, the terminal can determine the power control parameter set used for the first repetition according to the order of the IDs. The terminal can also determine the power control parameter set used for the first repetition according to the coding sequence corresponding to the information field of the power control parameter set indicated by the MAC-CE, or the terminal can determine the power control parameter set used for the first repetition from the valid power control parameter sets indicated by the MAC-CE, or can determine the power control parameter set used for the first repetition according to the ID of the power control parameter set.

[0523] The above application examples can be used when the network side device does not configure spatial related information (i.e., PUCCH-SpatialRelationInfo) for the terminal but configures pathlossReferenceRS. When the network side device does not configure pathlossReferenceRS for the terminal, the terminal can use the reference signal obtained through the SS / PBCH block with the same SS / PBCH block serial number as that used by the terminal to obtain the MIB as the path loss reference signal for all PUCCH repetitions of the PUCCH resource. Before the terminal is configured with power control parameters, the terminal can also use the reference signal obtained through the SS / PBCH block with the same SS / PBCH block serial number as that used by the terminal to obtain the MIB as the path loss reference signal for all PUCCH repetitions of the PUCCH resource.

[0524] In the uplink channel power control method of the embodiments of this application, the network side device dynamically indicates the information used to determine the transmission power of the uplink channel resource through the first target signaling. When the network side device does not configure the spatial setting signaling for the terminal, the network side device and the terminal can also have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of the M-TRP. And the network side device can be indicated in various ways such as the identification information, number, group, and indication information of the power control parameter of the power control parameter, and the indication method is flexible and changeable, and the operability is strong.

[0525] See Figure 2As shown in the figure, an embodiment of the present application further provides an uplink channel power control method, which is applied to a terminal. Among them, the uplink channel power control method applied to the terminal and the uplink channel power control method applied to the network side of the terminal are based on the same inventive concept. Since the uplink channel power control processes of the two are similar, the embodiments can be referred to each other, and the repeated parts will not be described again.

[0526] The uplink channel power control method of the embodiment of the present application includes:

[0527] Step 201: Receive a first target signaling, where the first target signaling indicates information for determining the transmission power of an uplink channel resource; where, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes at least one of the following: indication information of power control parameters, indication information of a set of power control parameters; the indication information of the power control parameters indicates one or more power control parameters through at least one of the following: identification information of the power control parameters, the number of power control parameters, and the group of the power control parameters.

[0528] Here, the terminal receives the first target signaling, and the network side device dynamically indicates the information for determining the transmission power of the uplink channel resource in the first target signaling. The terminal can determine the transmission power of the uplink channel resource based on the information dynamically indicated by the first target signaling. In this way, when the network side device does not configure a spatial setting signaling for the terminal, the terminal and the network side device can also have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of the M-TRP. Among them, the information for determining the transmission power of the uplink channel resource indicated in the first target signaling may include indication information of power control parameters, indication information of a set of power control parameters, and the indication information of the power control parameters may indicate one or more power control parameters in various ways such as indicating the identification information, number, and group of the power control parameters. In this way, the terminal can determine the transmission power in various ways such as the identification information, number, group, and indication information of the set of power control parameters of the power control parameters, with flexible and variable methods and strong operability.

[0529] Among them, the network side device can configure one or more power control parameters for the uplink channel resource through RRC signaling. The configured power control parameters may include at least one of the following: target received power P 0 , path loss reference signal, closed-loop reference signal, but not limited thereto.

[0530] Among them, the power control parameter configuration of the uplink channel resource may include one or more groups of power control parameters, and each group of power control parameters includes one or more power control parameters. The power control parameter configuration of the uplink channel resource may also include one or more sets of power control parameters, and each set of power control parameters includes one or more power control parameters. The multiple sets of power control parameters can also be divided into different groups, and each group of power control parameter sets includes one or more sets of power control parameters.

[0531] For example, assume that the power control parameter configuration of the uplink channel resource includes A power control parameters and / or B sets of power control parameters, where both A and B are integers greater than or equal to 1. The network-side device can indicate one or more power control parameters from the A power control parameters and / or the power control parameters included in the B sets of power control parameters through the indication information of the power control parameters. The terminal receives the indication information of the power control parameters and determines the transmission power of the uplink channel resource based on the indicated one or more power control parameters. Alternatively, the network-side device can also indicate one or more sets of power control parameters from the B sets of power control parameters through the indication information of the set of power control parameters. The terminal receives the indication information of the power control parameters and determines the transmission power of the uplink channel resource based on the indicated one or more power control parameters.

[0532] Optionally, the indication information of the set of power control parameters can indicate one or more sets of power control parameters through at least one of the following: the identification information of the set of power control parameters, the number of sets of power control parameters, the group of the set of power control parameters, but not limited to this.

[0533] At this time, the indication information of the set of power control parameters can indicate one or more sets of power control parameters in various ways such as the identification information, number, and group of the set of power control parameters. The terminal can determine the transmission power based on various ways such as the identification information, number, and group of the set of power control parameters, and the method is flexible and changeable.

[0534] Step 202: Determine the transmission power of the uplink channel resource according to the first target signaling.

[0535] Here, the terminal determines the transmission power of the uplink channel resource according to the information for determining the transmission power of the uplink channel resource indicated by the first target signaling, so that the terminal and the network-side device can have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of M-TRP.

[0536] In the uplink channel power control method of the embodiments of the present application, the network-side device dynamically indicates the information for determining the transmission power of the uplink channel resource in the first target signaling. The terminal can determine the transmission power of the uplink channel resource based on the information dynamically indicated by the first target signaling. When the network-side device does not configure the spatial setting signaling for the terminal, the terminal and the network-side device can also have a consistent understanding of the transmission power of the uplink channel resource, ensuring the normal operation of the uplink channel transmission of M-TRP. Moreover, the terminal can determine the transmission power in various ways such as the identification information, number, group of the power control parameters, and the indication information of the set of power control parameters. The method is flexible and changeable and highly operable.

[0537] The uplink channel resources referred to in the embodiments of this application include, but are not limited to, PUCCH (Physical Uplink Control Channel) resources and PUSCH (Physical Uplink Share Channel) resources.

[0538] Optionally, the first target signaling is a Media Access Control - Control Element (MAC - CE) signaling or Downlink Control Information (DCI), but is not limited thereto.

[0539] At this time, the network - side device can indicate the power control parameter and / or power control parameter set of the uplink channel resources triggered by DCI to the terminal through MAC - CE or DCI. The terminal receives the DCI, determines that it needs to transmit the uplink channel resources, and determines the transmission power of the uplink channel resources according to the power control parameter and / or power control parameter set indicated by MAC - CE or DCI. The network - side device does not configure the spatial setting signaling for the terminal, and the terminal and the network - side device can also have a consistent understanding of the transmission power of the uplink channel resources, ensuring the normal operation of the uplink channel transmission of M - TRP.

[0540] In the embodiments of this application, the terminal can determine one or more power control parameters used for the transmission power of the uplink channel resources through at least one of the identification information (such as ID) of the power control parameters indicated by the network - side device, the number of power control parameters, and the group of power control parameters; similarly, the terminal can determine one or more power control parameters used for the transmission power of the uplink channel resources through at least one of the identification information of the power control parameter set indicated by the network - side device, the number of power control parameter sets, and the group of power control parameters. The following describes these several methods as follows.

[0541] Method 1.1: The terminal determines the transmission power of the uplink channel resources according to the power control parameters corresponding to the identification information of the power control parameters indicated by the network - side device.

[0542] Optionally, the information for determining the transmission power of the uplink channel resources indicated by the first target signaling includes the indication information of the power control parameters. The indication information of the power control parameters indicates one or more power control parameters through the identification information of the power control parameters. The above - mentioned step 202 includes: The terminal determines the transmission power of the uplink channel resources according to the power control parameters corresponding to the multiple identification information indicated by the first target signaling.

[0543] For example, if the first target signaling (MAC - CE or DCI) indicates the power control parameter with ID 1 and the power control parameter with ID 2, the terminal determines the transmission power of the uplink channel resources according to these two power control parameters.

[0544] Method 1.2: The terminal determines the transmission power of the uplink channel resource according to the power control parameters in the power control parameter set corresponding to the identification information of the power control parameter set indicated by the network-side device.

[0545] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter set. The indication information of the power control parameter set indicates one or more power control parameter sets through the identification information of the power control parameter set. The above step 202 includes: The terminal determines the transmission power of the uplink channel resource according to the power control parameters in the one or more power control parameter sets indicated by the first target signaling.

[0546] For example, if the first target signaling (MAC-CE or DCI) indicates the power control parameter set with ID 1 and the power control parameter set with ID 2, the terminal determines the transmission power of the uplink channel resource according to the power control parameters in these two power control parameter sets.

[0547] Among them, when the network-side device indicates one or more power control parameter sets, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in the one or more power control parameter sets, or can select some power control parameters (such as the power control parameter with the smallest ID or the default power control parameter) according to the set rules in the one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0548] Method 1.3: The terminal determines the number of power control parameters used for the transmission power of the uplink channel resource according to the number of power control parameters indicated by the network-side device.

[0549] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter. The indication information of the power control parameter indicates one or more power control parameters through the number of power control parameters. The above step 202 includes: determining the number of power control parameters used for the transmission power of the uplink channel resource according to the number indicated by the indication information of the power control parameter.

[0550] At this time, the terminal determines the number of power control parameters used for the transmission power of the uplink channel resource based on the number of power control parameters indicated by the first target signaling. The terminal can select the corresponding number of power control parameters from the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0551] Among them, when the network-side device indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters according to the set rules (such as the power control parameter with the smallest ID or the default power control parameter) to determine the transmission power of the uplink channel resource

[0552] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal determines that the number of power control parameters used for the transmission power of the uplink channel resource is 1, and the terminal selects 1 power control parameter from the power control parameter configuration of the uplink channel resource according to the set rule to determine the transmission power of the uplink channel resource.

[0553] For another example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal determines that the number of power control parameters used for the transmission power of the uplink channel resource is 2, and the terminal selects 2 power control parameters from the power control parameter configuration of the uplink channel resource according to the set rule to determine the transmission power of the uplink channel resource.

[0554] Method 1.4: The terminal determines the number of power control parameter sets used for the transmission power of the uplink channel resource according to the number of power control parameter sets indicated by the network-side device.

[0555] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter set, and the indication information of the power control parameter set indicates one or more power control parameter sets through the number of power control parameter sets. The above step 202 includes: determining the number of power control parameter sets used for the transmission power of the uplink channel resource according to the number indicated by the indication information of the power control parameter set.

[0556] At this time, the terminal determines the number of power control parameter sets used for the transmission power of the uplink channel resource according to the number of power control parameter sets indicated by the first target signaling. The terminal can select the corresponding number of power control parameter sets from the power control parameter configuration of the uplink channel resource, and determine the transmission power of the uplink channel resource based on the power control parameters in the power control parameter sets.

[0557] Among them, when the network side indicates the number of power control parameter sets, the terminal can select the corresponding number of power control parameter sets according to the set rule (such as the power control parameter with the smallest ID or the default power control parameter). After the terminal selects the corresponding number of power control parameter sets, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in the corresponding number of power control parameter sets, or can also select some power control parameters (such as the power control parameter with the smallest ID or the default power control parameter) according to the set rule in the corresponding number of power control parameter sets to determine the transmission power of the uplink channel resource.

[0558] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal determines that the number of power control parameter sets used for the transmission power of the uplink channel resource is 1, and the terminal selects 1 power control parameter set from the power control parameter configuration of the uplink channel resource according to the set rule, and determines the transmission power of the uplink channel resource based on the power control parameters in the selected 1 power control parameter set.

[0559] Method 1.5: The terminal determines the power control parameter used for the transmission power of the uplink channel resource according to the group of power control parameters indicated by the network-side device.

[0560] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter. The indication information of the power control parameter indicates one or more groups of power control parameters through the group of power control parameters. The above step 202 includes: determining the power control parameter used for the transmission power of the uplink channel resource among the power control parameters indicated by the indication information of the power control parameter.

[0561] At this time, the terminal determines the power control parameter used for the transmission power of the uplink channel resource among the power control parameters indicated by the first target signaling according to the group of power control parameters. The terminal can select one or more power control parameters from the power control parameters indicated by the group to determine the transmission power of the uplink channel resource.

[0562] Among them, the network-side device indicates the group of power control parameters, and the terminal can select the power control parameter in the power control parameters of the specified group according to the set rule (such as the power control parameter with the smallest ID or the default power control parameter) to determine the transmission power of the uplink channel resource.

[0563] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters, the terminal determines the power control parameter used for the transmission power of the uplink channel resource among the first group of power control parameters. The terminal can select one or more power control parameters from the first group of power control parameters according to the set rule to determine the transmission power of the uplink channel resource.

[0564] For another example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters and the second group of power control parameters, the terminal determines the power control parameter used for the transmission power of the uplink channel resource among the first group of power control parameters and the second group of power control parameters. The terminal can select one or more power control parameters from the first group of power control parameters and the second group of power control parameters respectively according to the set rule to determine the transmission power of the uplink channel resource.

[0565] Method 1.6: The terminal determines the set of power control parameters used for the transmission power of the uplink channel resource according to the group of the set of power control parameters indicated by the network-side device.

[0566] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the set of power control parameters. The indication information of the set of power control parameters indicates one or more groups of sets of power control parameters through the group of the set of power control parameters. The above step 202 includes: determining the set of power control parameters used for the transmission power of the uplink channel resource among the sets of power control parameters indicated by the indication information of the set of power control parameters.

[0567] At this time, the terminal determines the power control parameter set used for the transmission power of the uplink channel resource from the power control parameter sets of the indicated group according to the group of the power control parameter set indicated by the first target signaling. Optionally, the terminal selects one or more power control parameter sets from the power control parameter sets of the indicated group, and determines the transmission power of the uplink channel resource based on the power control parameters in the selected power control parameter sets. Optionally, the terminal determines the transmission power of the uplink channel resource using all the power control parameter sets indicated by the first target signaling.

[0568] Optionally, the network device indicates the group of the power control parameter set, and the terminal can select one or more power control parameter sets from the power control parameter sets of the specified group according to the set rules. After the terminal selects one or more power control parameter sets, the terminal can determine the transmission power of the uplink channel resource according to all the power control parameters in the one or more power control parameter sets, or can also select some power control parameters (such as the power control parameter with the smallest ID or the default power control parameter) according to the set rules in the one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0569] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal determines the power control parameter set used for the transmission power of the uplink channel resource from the first group of power control parameter sets. The terminal can select one or more power control parameter sets according to the set rules from the first group of power control parameter sets, and determine the transmission power of the uplink channel resource based on the power control parameters in the selected power control parameter sets.

[0570] In the above methods 1.2 to 1.6, when the first target signaling indicates the number of power control parameters, the group, or the identification information, number, and group of the power control parameter set, the terminal can select some power control parameters or power control parameter sets according to a certain method. For the method of selecting some power control parameters or power control parameter sets, refer to the following introduction.

[0571] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameters. The first target signaling indicates one or more power control parameters from any one of the following 2.1-2.4:

[0572] 2.1 The default power control parameters in the power control parameter configuration of the uplink channel resource.

[0573] Optionally, when the first target signaling indicates the identification information of the power control parameters, the first target signaling can indicate the identification information of one or more power control parameters from the default power control parameters in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameters corresponding to the indicated identification information to determine the transmission power of the uplink channel resource.

[0574] Optionally, when the first target signaling indicates the number of power control parameters, the terminal may select the corresponding number of default power control parameters from the default power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0575] Among them, if the number of power control parameters indicated by the first target signaling is less than the number of default power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the smaller one is preferred.

[0576] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal selects 1 default power control parameter with the smallest identifier from the default power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0577] Among them, if the number of power control parameters indicated by the first target signaling is greater than the number of default power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more default power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with a specific value).

[0578] Optionally, when the first target signaling indicates the group of power control parameters, the terminal may select one or more default power control parameters from the default power control parameters of the power control parameters indicating the group to determine the transmission power of the uplink channel resource.

[0579] Among them, if the number of default power control parameters included in the power control parameters indicated by the first target signaling is greater than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the smaller one is preferred.

[0580] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameters, the terminal selects 2 default power control parameters with the smallest identifiers from the default power control parameters in the first group of power control parameters to determine the transmission power of the uplink channel resource.

[0581] Among them, if the number of default power control parameters included in the power control parameters indicated by the first target signaling is less than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more default power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with a specific value).

[0582] Among them, the default power control parameters can be configured by the network side or agreed by the protocol.

[0583] Among them, the default power control parameter may be the power control parameter with the smallest identifier, but is not limited thereto.

[0584] In the power control parameter configuration of the uplink channel resource described in 2.2, among the top N or bottom N power control parameters; N is an integer greater than or equal to 1; the power control parameters are sorted according to the identifier size or the configuration order.

[0585] Optionally, when the first target signaling indicates the identifier information of the power control parameter, the first target signaling indicates the identifier information of one or more power control parameters from the top N or bottom N power control parameters in the power control parameter configuration of the uplink channel resource, and the terminal uses the power control parameter corresponding to the indicated identifier information to determine the transmission power of the uplink channel resource.

[0586] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters from the top N or bottom N power control parameters in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0587] Among them, if the number of power control parameters indicated by the first target signaling is less than N, it can be agreed in the protocol that the power control parameter with a smaller identifier or the default power control parameter is preferred.

[0588] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 1, the terminal selects the power control parameter with the smallest identifier ranked first from the top 2 power control parameters in the power control parameter configuration of the uplink channel resource (N equals 2, and the power control parameters are sorted in ascending order of the identifier) to determine the transmission power of the uplink channel resource.

[0589] Among them, if the number of power control parameters indicated by the first target signaling is greater than N, it can be agreed in the protocol to reuse one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with the identifier value being a specific value).

[0590] Optionally, when the first target signaling indicates the group of power control parameters, the terminal can select one or more power control parameters from the top N or bottom N power control parameters in the power control parameters of the indicated group to determine the transmission power of the uplink channel resource.

[0591] Among them, when the first target signaling indicates the group of power control parameters, if N is greater than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the power control parameter with a smaller identifier or the default power control parameter is preferred.

[0592] For example, if the first target signaling (MAC-CE or DCI) indicates the first set of power control parameters, the terminal selects the power control parameter with the smallest identifier ranked first among the first 2 power control parameters in the first set of power control parameters (N = 2, and the power control parameters are sorted in ascending order of the identifier) to determine the transmission power of the uplink channel resource.

[0593] Among them, when the first target signaling indicates the group of power control parameters, if N is less than the number of power control parameters used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with the identifier value being a specific value).

[0594] Among the default power control parameters in the set of power control parameters included in the power control parameter configuration described in 2.3.

[0595] Optionally, when the first target signaling indicates the identifier information of the power control parameter, the first target signaling indicates the identifier information of one or more power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameter corresponding to the indicated identifier information to determine the transmission power of the uplink channel resource.

[0596] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of default power control parameters from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0597] Among them, if the number of power control parameters indicated by the first target signaling is less than the number of default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the power control parameter with the smallest identifier is preferred.

[0598] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal selects 2 default power control parameters with the smallest identifiers from the default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0599] Among them, if the number of power control parameters indicated by the first target signaling is greater than the number of default power control parameters in the set of power control parameters included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with the identifier value being a specific value).

[0600] The power control parameter configuration of the uplink channel resource includes the power control parameters ranked in the first M or the last M positions in the power control parameter set; M is an integer greater than or equal to 1; the power control parameters are sorted according to the identifier size or the configuration order.

[0601] Optionally, when the first target signaling indicates the identifier information of the power control parameter, the first target signaling indicates the identifier information of one or more power control parameters from the power control parameters ranked in the first M or the last M positions in the power control parameter set included in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameters corresponding to the indicated identifier information to determine the transmission power of the uplink channel resource.

[0602] Optionally, when the first target signaling indicates the number of power control parameters, the terminal can select the corresponding number of power control parameters from the power control parameters ranked in the first M or the last M positions in the power control parameter set included in the power control parameter configuration of the uplink channel resource to determine the transmission power of the uplink channel resource.

[0603] Among them, if the number of power control parameters indicated by the first target signaling is less than M, it can be agreed in the protocol that the power control parameter with a smaller identifier or the default power control parameter is preferred.

[0604] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameters is 2, the terminal selects the power control parameters with the first 2 smaller identifiers from the power control parameters ranked in the first 4 positions in the power control parameter set included in the power control parameter configuration of the uplink channel resource (M is equal to 4, and the power control parameters are sorted in ascending order of the identifier) to determine the transmission power of the uplink channel resource.

[0605] Among them, if the number of power control parameters indicated by the first target signaling is greater than M, it can be agreed in the protocol to multiplex one or more power control parameters, or add other specific power control parameters (such as the power control parameter with the smallest identifier or the power control parameter with the identifier value being a specific value).

[0606] Optionally, the information for determining the transmission power of the uplink channel resource indicated by the first target signaling includes the indication information of the power control parameter set, and the first target signaling indicates one or more power control parameter sets from any one of the following 2.5-2.8.

[0608] The above step 202 includes: determining the transmission power of the uplink channel resource according to the default power control parameters in the indicated power control parameter set.

[0609] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling may indicate the identification information of one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource. The terminal uses the default power control parameters in the indicated one or more power control parameter sets to determine the power control parameters for the transmission power of the uplink channel resource.

[0610] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal may select the corresponding number of power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and use the default power control parameters in the corresponding number of power control parameter sets to determine the transmission power of the uplink channel resource.

[0611] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to identify the smaller power control parameter set or the default power control parameter set as preferred.

[0612] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identification from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and uses the default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0613] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identification or the power control parameter set with the identification value being a specific value).

[0614] Optionally, when the first target signaling indicates the group of the power control parameter set, the terminal selects one or more power control parameter sets from the power control parameter sets of the indicated group, and uses the default power control parameters in the one or more power control parameter sets to determine the transmission power of the uplink channel resource.

[0615] Among them, when the first target signaling indicates the group of the power control parameter set, if the number of power control parameter sets included in the power control parameter set of the indicated group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to identify the smaller power control parameter set or the default power control parameter set as preferred.

[0616] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects the power control parameter set with the smallest identification in the first group of power control parameter sets, and uses one or more default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0617] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as identifying the smallest power control parameter set or the power control parameter set with a specific value).

[0618] Among them, the default power control parameter set can be configured by the network-side device or can be agreed by the protocol.

[0619] Among them, the default power control parameter set can be the power control parameter set identifying the smallest one, but not limited to this.

[0620] Among the power control parameter sets included in the power control parameter configuration of the uplink channel resource described in 2.6.

[0621] The above step 202 includes: determining the transmission power of the uplink channel resource according to the power control parameters ranked in the first P positions or the last P positions in the indicated power control parameter set; P is an integer greater than or equal to 1; the power control parameters are sorted according to the identification size or the configuration order.

[0622] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling can indicate the identification information of one or more power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and the terminal uses the power control parameters ranked in the first P positions or the last P positions in the indicated one or more power control parameter sets to determine the power control parameters of the transmission power of the uplink channel resource.

[0623] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal can select the corresponding number of power control parameter sets from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and the power control parameters ranked in the first P positions or the last P positions in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0624] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol that the power control parameter set with a smaller identification or the default power control parameter set is preferred.

[0625] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identifier from the power control parameter sets included in the power control parameter configuration of the uplink channel resource, and uses the 2 power control parameters with the smallest identifiers in this 1 power control parameter set (P = 2, and the power control parameters are sorted in ascending order of the identifier) to determine the transmission power of the uplink channel resource.

[0626] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0627] Optionally, when the first target signaling indicates the group of the power control parameter set, the terminal can select one or more power control parameter sets from the power control parameter sets indicating the group, and the first P or last P power control parameters in this one or more power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0628] Among them, when the first target signaling indicates the group of the power control parameter set, if the number of power control parameter sets included in the power control parameter set indicating the group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol that the power control parameter set with the smallest identifier or the default power control parameter set is preferred.

[0629] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects the power control parameter set with the smallest identifier in the first group of power control parameter sets, and uses the first power control parameter with the smallest identifier in this 1 power control parameter set (P = 1, and the power control parameters are sorted in ascending order of the identifier) to determine the transmission power of the uplink channel resource.

[0630] Among them, when the first target signaling indicates the group of the power control parameter set, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with a specific identifier value).

[0631] In the default power control parameter set in the power control parameter configuration of the uplink channel resource described in 2.7.

[0632] The above step 202 includes: determining the transmission power of the uplink channel resource according to the default power control parameter in the indicated power control parameter set.

[0633] Optionally, when the first target signaling indicates the identification information of the power control parameter set, the first target signaling may indicate the identification information of one or more power control parameter sets from the power control parameter configurations of the uplink channel resources including the default power control parameter sets, and the terminal uses the default power control parameters in the one or more power control parameter sets corresponding to the identification information to determine the power control parameters of the transmission power of the uplink channel resources.

[0634] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal selects the corresponding number of power control parameter sets from the default power control parameter sets included in the power control parameter configurations of the uplink channel resources, and the default power control parameters in the corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resources.

[0635] Among them, if the number of power control parameter sets indicated by the first target signaling is less than the number of default power control parameter sets included in the power control parameter configuration of the uplink channel resources, it can be agreed in the protocol that the smaller power control parameter set is marked as preferred.

[0636] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest default identification from the default power control parameter sets included in the power control parameter configuration of the uplink channel resources, and uses the default power control parameters in this 1 default power control parameter set to determine the transmission power of the uplink channel resources.

[0637] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than the number of power control parameter sets included in the power control parameter configuration of the uplink channel resources, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identification or the power control parameter set with an identification value of a specific value).

[0638] Optionally, when the first target signaling indicates the group of the power control parameter sets, the terminal may select one or more power control parameter sets from the default power control parameter sets in the power control parameter sets indicating the group, and the default power control parameters in the one or more power control parameter sets are used to determine the transmission power of the uplink channel resources.

[0639] Among them, when the first target signaling indicates the group of the power control parameter sets, if the number of default power control parameter sets included in the power control parameter sets indicating the group is greater than the number of power control parameter sets used to determine the transmission power of the uplink channel resources, it can be agreed in the protocol that the smaller power control parameter set is marked as preferred.

[0640] For example, if the first target signaling (MAC-CE or DCI) indicates the first set of power control parameter sets, the terminal selects, from the default power control parameter sets in the first set of power control parameter sets, the top 2 default power control parameter sets sorted in ascending order of the identifier, and uses the default power control parameters in these 2 power control parameter sets to determine the transmission power of the uplink channel resource.

[0641] Among them, when the first target signaling indicates the group of the power control parameter sets, if the number of power control parameter sets included in the power control parameter set indicating the group is less than the number of power control parameter sets used to determine the transmission power of the uplink channel resource, it can be agreed in the protocol to reuse one or more power control parameter sets, or add other specific power control parameter sets (such as the power control parameter set with the smallest identifier or the power control parameter set with the identifier taking a specific value).

[0642] Among the power control parameter sets ranked in the top Q bits or the last Q bits in the power control parameter configuration of the uplink channel resource described in 2.8.

[0643] The above step 202 includes: determining the transmission power of the uplink channel resource according to the default power control parameters in the indicated power control parameter sets; Q is an integer greater than or equal to 1; the power control parameter sets are sorted in ascending order of the identifier or in the configured order.

[0644] Optionally, when the first target signaling indicates the identifier information of the power control parameter set, the first target signaling can indicate the identifier information of one or more power control parameter sets from the power control parameter sets ranked in the top Q bits or the last Q bits in the power control parameter configuration of the uplink channel resource, and the terminal uses the default power control parameters in the corresponding one or more power control parameter sets corresponding to the identifier information to determine the power control parameters of the transmission power of the uplink channel resource.

[0645] Optionally, when the first target signaling indicates the number of power control parameter sets, the terminal can select the corresponding number of power control parameter sets from the power control parameter sets ranked in the top Q bits or the last Q bits in the power control parameter configuration of the uplink channel resource, and the default power control parameters in these corresponding number of power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0646] Among them, if the number of power control parameter sets indicated by the first target signaling is less than Q, it can be agreed in the protocol that the power control parameter set with a smaller identifier or the default power control parameter set is preferred.

[0647] For example, if the first target signaling (MAC-CE or DCI) indicates that the number of power control parameter sets is 1, the terminal selects 1 power control parameter set with the smallest identifier from the power control parameter sets ranked in the top 4 bits in the power control parameter configuration of the uplink channel resource (Q is equal to 4, and the power control parameter sets are sorted in ascending order of the identifier), and uses the default power control parameters in this 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0648] Among them, if the number of power control parameter sets indicated by the first target signaling is greater than Q, it can be agreed in the protocol to multiplex one or more power control parameter sets, or add other specific power control parameter sets (such as identifying the smallest power control parameter set or the power control parameter set with a specific value).

[0649] Optionally, when the first target signaling indicates the group of power control parameter sets, the terminal can select one or more power control parameter sets from the power control parameter sets ranked in the first Q positions or the last Q positions in the indicated group of power control parameter sets, and the default power control parameters in the one or more power control parameter sets are used to determine the transmission power of the uplink channel resource.

[0650] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the indicated group of power control parameter sets is greater than Q, it can be agreed in the protocol that the power control parameter set with a small identifier or the default power control parameter set is preferred.

[0651] For example, if the first target signaling (MAC-CE or DCI) indicates the first group of power control parameter sets, the terminal selects 1 power control parameter set with the smallest identifier from the power control parameter sets ranked in the first 2 positions in the first group of power control parameter sets (Q is equal to 2, and the power control parameter sets are sorted in ascending order of the identifier), and uses the default power control parameters in the 1 power control parameter set to determine the transmission power of the uplink channel resource.

[0652] Among them, when the first target signaling indicates the group of power control parameter sets, if the number of power control parameter sets included in the indicated group of power control parameter sets is less than Q, it can be agreed in the protocol to multiplex one or more power control parameter sets, or add other specific power control parameter sets (such as identifying the smallest power control parameter set or the power control parameter set with a specific value).

[0653] The embodiments of the present application can flexibly determine the power control parameters or power control parameter sets used for the transmission power of the uplink channel resource through the above various methods.

[0654] In the embodiments of the present application, when determining the transmission power of the uplink channel resource under M-TRP, it is also necessary to determine the correspondence between the repeated copies of the uplink channel resource and the power control parameters or power control parameter sets. This correspondence can be indicated by the network-side device or agreed in the protocol. The following introduces how to determine the correspondence between the repeated copies of the uplink channel resource and the power control parameters or power control parameter sets.

[0655] Optionally, step 202 above includes:

[0656] Determine the first power control parameter based on the first preset index;

[0657] Determine the transmission power of the first repeated copy of the uplink channel resource using the first power control parameter.

[0658] Here, the terminal can determine the first power control parameter based on a first preset metric, and use the first power control parameter to determine the transmission power of the first repeated copy of the uplink channel resource.

[0659] When the correspondence between the repeated copies of the uplink channel resource and the power control parameter or set of power control parameters is agreed upon through a protocol, it can be agreed that the terminal determines the first power control parameter based on a first preset metric. When the network side device indicates the correspondence between the repeated copies of the uplink channel resource and the power control parameter or set of power control parameters, if the network side device indicates the correspondence between the group of power control parameters and the repeated copies of the uplink channel resource, or the network side device indicates the identification information, group, and correspondence between the repeated copies of the uplink channel resource of the set of power control parameters, it can also be agreed that the terminal determines the first power control parameter based on a first preset metric. The following will be introduced separately.

[0660] When determining the correspondence between the repeated copies of the uplink channel resource and the power control parameter or set of power control parameters through a protocol agreement, it includes but is not limited to the following agreement methods:

[0661] Method 3.1: If the network side device indicates the identification information of the power control parameter through a first target signaling, it can be agreed that the terminal determines the first power control parameter from the power control parameters corresponding to the identification information based on a first preset metric.

[0662] Method 3.2: If the network side device indicates the number of power control parameters through a first target signaling, after the terminal selects the corresponding number of power control parameters in the foregoing manner, it can be agreed that the terminal determines the first power control parameter from the corresponding number of power control parameters based on a first preset metric.

[0664] Method 3.4: If the network side device indicates multiple groups of power control parameters through a first target signaling, it can be agreed that the terminal selects a group of power control parameters from the indicated multiple groups of power control parameters based on a first preset metric, and determines the first power control parameter from the selected group of power control parameters based on a first preset metric. The first preset metrics used twice can be the same or different metrics.

[0665] Method 3.5: If the network-side device indicates the identification information of a power control parameter set through a first target signaling, through protocol agreement, the terminal selects one or more power control parameters from this power control parameter set based on a first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in this power control parameter set as the first power control parameter.

[0666] Method 3.6: If the network-side device indicates the identification information of multiple power control parameter sets through a first target signaling, through protocol agreement, the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on a first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that after the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, it uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0667] Method 3.7: If the network-side device indicates that the number of power control parameter sets is 1 through a first target signaling, after the terminal selects a power control parameter set in the foregoing manner, through protocol agreement, the terminal selects one or more power control parameters from this power control parameter set based on a first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in this power control parameter set as the first power control parameter.

[0668] Method 3.8: If the network-side device indicates that the number of power control parameter sets is multiple through a first target signaling, after the terminal selects multiple power control parameter sets in the foregoing manner, through protocol agreement, the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on a first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that after the terminal selects one or more power control parameter sets from these multiple power control parameter sets based on the first preset metric, it uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0669] Method 3.9: If the network-side device indicates a set of power control parameter sets through the first target signaling, through protocol agreement, the terminal selects one or more power control parameter sets from this set of power control parameter sets based on the first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that the terminal selects one or more power control parameter sets from this set of power control parameter sets based on the first preset metric and uses all the power control parameters in this one or more power control parameter sets as the first power control parameter.

[0670] Method 3.10: If the network-side device indicates multiple sets of power control parameter sets through the first target signaling, through protocol agreement, the terminal selects one set of power control parameter sets from these multiple sets of power control parameter sets based on the first preset metric, then continues to select one or more power control parameter sets from this one set of power control parameter sets based on the first preset metric, and then continues to select one or more power control parameters from this one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used three times can be the same or different metrics; or it is agreed that the terminal selects one set of power control parameter sets from these multiple sets of power control parameter sets based on the first preset metric, and then after continuing to select one or more power control parameter sets from this one set of power control parameter sets based on the first preset metric, uses all the power control parameters in this one or more power control parameter sets as the first power control parameter, where the first preset metrics used twice can be the same or different metrics.

[0671] When the network-side device indicates the correspondence between the uplink channel resource repeated replicas and the power control parameters or power control parameter sets, it includes but is not limited to the following agreement methods:

[0672] Method 4.1: If the network-side device indicates the correspondence between the group of power control parameters and the first repeated replica of the uplink channel resource, after the terminal determines the power control parameters of the group corresponding to the first repeated replica according to the correspondence, through protocol agreement, the terminal selects one or more power control parameters from the power control parameters of the group corresponding to the first repeated replica based on the first preset metric as the first power control parameter.

[0673] Method 4.2: If the network-side device indicates the correspondence between the identification information of the power control parameter set and the first repeated replica of the uplink channel resource, after the terminal determines the power control parameter set corresponding to the first repeated replica according to the correspondence, through protocol agreement, the terminal selects one or more power control parameters from the power control parameter set corresponding to the first repeated replica based on the first preset metric as the first power control parameter; or it is agreed that the terminal uses all the power control parameters in the power control parameter set corresponding to the first repeated replica as the first power control parameter.

[0674] Method 4.3: If the network device indicates the correspondence between the group of power control parameter sets and the first repeated copy of the uplink channel resource, after the terminal determines the power control parameter set of the group corresponding to the first repeated copy according to the correspondence, through protocol agreement, the terminal can select one or more power control parameter sets from the power control parameter sets of the group corresponding to the first repeated copy based on the first preset metric, and continue to select one or more power control parameters from the one or more power control parameter sets based on the first preset metric as the first power control parameter, where the first preset metrics used twice can be the same or different metrics; or it is agreed that the terminal selects one or more power control parameter sets from the power control parameter sets of the group corresponding to the first repeated copy based on the first preset metric, and uses all the power control parameters in the one or more power control parameter sets as the first power control parameter.

[0675] In the embodiments of the present application, the first power control parameter corresponding to the first repeated copy of the uplink channel resource can be determined through the above-mentioned multiple methods. Optionally, for other repeated copies of the uplink channel resource, the repeated copies belonging to the same group as the first repeated copy can use the same power control parameters as the first repeated copy; the repeated copies not belonging to the same group as the first repeated copy can use different power control parameters from the first repeated copy.

[0676] Among them, the first repeated copy of the uplink channel resource refers to the copy of the initial transmission of the uplink channel resource.

[0677] In the embodiments of the present application, the network device can indicate the correspondence between the power control parameters or power control parameter sets and the repeated copies of the uplink channel resource to the terminal through the first target signaling or the second target signaling. Optionally, the above step 202 includes any one of the following:

[0678] Determine the power control parameter for the transmission power of the first repeated copy of the uplink channel resource according to the identification information or group of the power control parameters indicated in the first target signaling or the second target signaling and the information on the correspondence with the repeated copies of the uplink channel resource;

[0679] Determine the power control parameter for the transmission power of the first repeated copy of the uplink channel resource according to the identification information or group of the power control parameter sets indicated in the first target signaling or the second target signaling and the information on the correspondence with the repeated copies of the uplink channel resource;

[0680] Among them, the first target signaling is different from the second target signaling.

[0681] At this time, the network-side device can indicate the power control parameter or the identification information or group of the power control parameter set or the information on the correspondence relationship between the group and the duplicate of the uplink channel resource through the second target signaling. The network-side device can also carry, in the first target signaling, the information on the correspondence relationship between the power control parameter or the identification information or group of the power control parameter set and the duplicate of the uplink channel resource. The terminal determines the power control parameter corresponding to the duplicate of the uplink channel resource according to the information on the correspondence relationship between the power control parameter or the identification information or group of the power control parameter set indicated by the first target signaling or the second target signaling.

[0682] Among them, if the first target signaling or the second target signaling indicates the information on the correspondence relationship between the identification information of the power control parameter and the first duplicate of the uplink channel resource, the terminal can directly use the power control parameter corresponding to the identification of the first duplicate of the uplink channel resource as the first power control parameter to determine its transmission power. For other duplicates, the duplicates belonging to the same group as the first duplicate can use the same power control parameter as the first duplicate, and the duplicates not belonging to the same group as the first duplicate can use different power control parameters from the first duplicate.

[0683] For example, the network-side device indicates, through the first target signaling, the power control parameter with an identification (such as ID) value of 3 and the power control parameter with an ID value of 4, and indicates, through the first target signaling, the information on the correspondence relationship between the power control parameter with an ID value of 3 and the first duplicate of the uplink channel resource. The terminal uses the power control parameter with an ID value of 3 to determine the transmission power of the first duplicate and the duplicates belonging to the same group as the first duplicate, and the terminal uses the power control parameter with an ID value of 4 to determine the transmission power of the duplicates not belonging to the same group as the first duplicate.

[0684] Of course, the first target signaling or the second target signaling can also indicate the information on the correspondence relationship between the identification information of the power control parameter and multiple duplicates of the uplink channel resource. When the correspondence relationship of multiple duplicates is indicated, each duplicate uses the power control parameter in the power control parameter corresponding to its own identification to determine its transmission power.

[0685] When the first target signaling or the second target signaling indicates the information on the correspondence relationship between the group of the power control parameter, the identification information of the power control parameter set or the group of the power control parameter set and the first duplicate of the uplink channel resource, the first power control parameter used by the first duplicate of the uplink channel resource can be determined based on the first preset index with reference to the above methods 4.1 - 4.3.

[0686] Of course, the first target signaling or the second target signaling may also indicate the power control parameter group, the identification information of the power control parameter set, or the information on the correspondence between the group of the power control parameter set and multiple duplicate copies of the uplink channel resource. When the correspondence between multiple duplicate copies is indicated, each duplicate copy uses its corresponding power control parameter or power control parameter set, and determines its transmission power by referring to the above methods 4.1 - 4.3, which will not be elaborated here.

[0687] Among them, as described above, the first target signaling may be MAC-CE or DCI.

[0688] Among them, the second target signaling may be the downlink control information DCI, and the identification information or group of the power control parameter and the information on the correspondence with the duplicate copy of the uplink channel resource, or the identification information or group of the power control parameter set and the information on the correspondence with the duplicate copy of the uplink channel resource are indicated by the transmit power control (TPC) field of the DCI.

[0689] At this time, the network-side device indicates the identification information or group of the power control parameter and the information on the correspondence with the duplicate copy of the uplink channel resource, or the identification information or group of the power control parameter set and the information on the correspondence with the duplicate copy of the uplink channel resource through the TPC (Transmit Power Control) field in the DCI.

[0690] For example, the network-side device indicates through the MAC-CE that the number of power control parameter sets of the uplink channel resource is 1, and indicates through the TPC field in the DCI that the power control parameter set corresponding to the duplicate copy of the uplink channel resource (when not specifying a certain duplicate copy, it is default applicable to all duplicate copies) is the first power control parameter set (the first power control parameter set can be any one in the power control parameter set configuration of the uplink channel resource, or the first power control parameter set is the power control parameter set ranked first in the power control parameter set configuration of the uplink channel resource according to the configured order). The terminal uses the power control parameters in the first power control parameter set to determine the transmission power of the duplicate copy of the uplink channel resource.

[0691] For another example, the network-side device indicates that the number of power control parameter sets for the uplink channel resources is 2 through MAC-CE, and indicates that the power control parameter set corresponding to the uplink channel resource repetition copy (when not specifying a certain repetition copy, it is default applicable to all repetition copies) is the first power control parameter set through the TPC field in DCI (the first power control parameter set can be any one in the power control parameter set configuration of the uplink channel resources, or the first power control parameter set is the power control parameter set that is ranked first in the power control parameter set configuration of the uplink channel resources according to the configured order). At this time, there is a difference between the number of power control parameter sets indicated by MAC-CE and the number of power control parameter sets indicated by the TPC field in DCI. The terminal can determine the open-loop power control parameters (P 0 , path loss reference signal, closed-loop power control parameters, etc.) of the uplink channel resources according to the two power control parameter sets, and perform closed-loop power control adjustment on the corresponding uplink channel resource repetition copy according to the first power control parameter set.

[0692] Next, the first preset index in the embodiments of the present application will be introduced.

[0693] Optionally, the first preset index includes any one of the default power control parameters, the value of the identifier of the power control parameter itself, the size of the identifier of the power control parameter, the information field of the first target signaling, the order of the power control parameters indicated by the first target signaling, and the coding sequence corresponding to the power control parameters indicated by the first target signaling, and / or, the effective state of the power control parameters indicated by the first target signaling, and / or, the sorting of the groups of the power control parameters; and / or

[0694] The first preset index includes any one of the default power control parameter set, the value of the identifier of the power control parameter set itself, the size of the identifier of the power control parameter set, the sorting of the groups of the power control parameter set, the order of the power control parameter set indicated by the first target signaling, and the coding sequence corresponding to the power control parameter set indicated by the first target signaling, and / or, the effective state of the power control parameter set indicated by the first target signaling, and / or, the sorting of the groups of the power control parameter set.

[0695] Among them, the default power control parameters or power control parameter set can be configured by the network side or agreed by the protocol. The default power control parameters or power control parameter set can be the power control parameters or power control parameter set with the smallest identifier (such as ID).

[0696] At this time, the terminal can use the default power control parameters or power control parameter set as an index to select the first power control parameter.

[0697] For example, the network-side device indicates the first group of power control parameters through the first target signaling, and the terminal can select the default power control parameters in the first group of power control parameters as the first power control parameter used for the first repetition copy.

[0698] Among them, the value of the identifier (such as ID) itself represents the defined value of the identifier, while the size of the identifier represents the size compared with other identifiers. For example, for the power control parameter with ID equal to 5, the value of the identifier itself is 5. Compared with the power control parameter with ID equal to 0, its identifier is larger, and compared with the power control parameter with ID equal to 7, its identifier is smaller.

[0699] Optionally, the step of determining the first power control parameter based on the first preset index includes:

[0700] Determining the first power control parameter according to the power control parameter whose value of the identifier itself is the first preset value;

[0701] Determining the first power control parameter according to the power control parameters in the set of power control parameters whose value of the identifier itself is the second preset value;

[0702] Determining the first power control parameter according to the power control parameter whose identifier size is at the first preset level;

[0703] Determining the first power control parameter according to the power control parameters in the set of power control parameters whose identifier size is at the second preset level;

[0704] Among them, the identifier size being at the first preset level or the identifier size being at the second preset level includes any one of the following: the identifier is the smallest, the identifier is the largest, the identifier size is at the intermediate value, but is not limited thereto.

[0705] At this time, through protocol agreement, the terminal can determine the first power control parameter used for the first repeated copy according to the value of the identifier itself (the power control parameter with the identifier value being the first preset value or the set of power control parameters with the identifier value being the second preset value) or the identifier size (the power control parameter or the set of power control parameters with the smallest, largest or intermediate identifier) among the power control parameters or the set of power control parameters indicated by the first target signaling.

[0706] Specifically, the power control parameter whose value of the identifier itself is the first preset value can be determined as the first power control parameter; or the power control parameters in the set of power control parameters whose value of the identifier itself is the second preset value can be determined as the first power control parameter; or the power control parameter whose identifier size is at the first preset level can be determined as the first power control parameter; or the power control parameters in the set of power control parameters whose identifier size is at the second preset level can be determined as the first power control parameter.

[0707] For example, the network-side device indicates the power control parameters with ID 1 and ID 2 through the first target signaling. The terminal selects the one with the smallest ID, that is, the power control parameter with ID 1, as the first power control parameter used for the first repeated copy based on the identifier size.

[0708] For another example, the network-side device indicates, via a first target signaling, that the number of power control parameters is 2.

[0714] For example, at least some of the information fields include 1 bit of indication information for indicating whether the power control parameters and / or power control parameter sets corresponding to this information field are valid. If the indication is valid, the power control parameters and / or power control parameter sets corresponding to the information field may be used to determine the transmission power of the uplink channel resource. If the indication is invalid, the control parameters and / or power control parameter sets corresponding to the information field are not used to determine the transmission power of the uplink channel resource.

When indicating that the uplink channel resource is associated with a set of power control parameters, it also indicates which set of power control parameters the first repeated copy is associated with.

[0725] For example, if the network-side device indicates four power control parameters through four information fields, the terminal may, based on the order of the information fields, select the power control parameter indicated by the first information field as the first power control parameter; or the terminal may, based on the order of the information fields and the valid status of the power control parameters, select the first valid power control parameter in the order of the information fields among the indicated valid power control parameters.
